性之高電壓情況下，在第二圖中之期間TP，如例示，在接 通第一開關元件7,斷開第二開關元件8及第三開關元件9 的狀態下，以較高速重複第四開關元件1〇之接通、斷開。 此時，僅在第四開關元件10接通的狀態下，於輸出部11a、 12a間發生具有與直流電源14之輸出電壓大致同等大小的 電壓值，且具有與該第四開關元件10連續地接通之時間 (接通時間）大致同等的脈寬之正極性的脈衝電壓（矩形 波狀之脈衝電壓），其施加於繞組變壓器5之初級繞組5a。 因此’在圖中之期間TP，藉由重複第四開關元件1〇之接 通、斷開，與其接通、斷開波形20相同波形之電壓’亦即 時間序列地排列複數正極性之脈衝電壓而構成的正極侧脈 衝行’自輸出部11a、12a施加於初級繞組5a。 此時，在期間TP (以下，稱為正極側脈衝行輸出期間 TP)内’藉由預先適切地設定第四開關元件10接通之時序 (正極侧脈衝行之各脈衝電壓的發生時序），及第四開關元 件10之接通時間（正極側脈衝行之各脈衝電壓的脈寬）， 可在繞組變壓器5之次級繞組5b上，如第二圖最下段之圖 所示’發生正極性之脈衝狀（凸型狀）的高電壓VP。 更詳細而言’本實施形態，正極側脈衝行輸出期間TP 中第四開關元件10之接通、斷開波形20由：前半侧接通、 斷開波形20a與後半側接通、斷開波形2〇b而構成。而後，

如第六（A)圖所示，重疊於繞組變壓器5之次級繞組5b上 發生之交流高電壓（第三圖）之峰值波形的PD檢測信號， 輸入第五圖（A)所示之高通濾波器31的輸入部。 高通濾波器31藉由前述R1及C1構成之濾波器，而 產生PD檢測信號，作為第六（B)圖所示之高頻信號。 該高頻信號輸入單觸發計時器32，如第六（C)圖所示， 形成具有微電腦（CPU) 33可檢測之時間寬（如2(^sec) 的方形波之波形。 詳細而言，在第五圖所示之單觸發計時器32中，輸入 其中之信號（B)係高位準（H)時，電晶體Q1斷開，因 此電阻R2之電壓低，由於經由電阻R3而接續之電晶體 Q2的基極電壓亦低，因此，電晶體Q2亦斷開。因而，電 容C2經由施加直流電壓Vcc之電阻R4而充電，電阻R4 與電容C2之接續點上的電壓信號為Η。該電壓信號藉由2 個倒相器II及12而依序反轉，成為第六（C)圖所示之特定 20 200922063 時間寬的脈衝信號而輸出，並輸入CPU33。另外，輸入信 號（B)為低位準（L与0)時，電晶體Q1接通，因此電阻 R2之電壓高（与Vcc)，由於其經由電阻R3而施加於電晶 體Q2的基極，因此，電晶體Q2亦斷開。因而，電容C2 放電，電阻R4與電容C2之接續點上的電壓信號為L。 CPU33如上述，統計自單觸發計時器32輸出之脈衝 數，超過預先設定之數量（如每1秒鐘之數量）N時，判 定為微放電。結果自CPU33傳送遮斷對電源電路3之電源 . · · · 供給的信號至第一圖之控制電路4，並且傳送使其點燈或 熄燈之警報信號至離子產生裝置之框體的正面等上配置的 LED等警報顯示器34。藉由此等處理，亦即電源供給之遮 斷，可防止電源電路3及離子產生裝置本體起火、燒損等 事故，藉由警報顯示通報放電電極之絕緣性降低，而督促 除去附著於電極周邊之碳及污垢。

The switching element is turned on, off, and turned on. The south power supply circuit 3 is provided with a winding transformer 5' having an initial stage winding 5a and a secondary winding 5b, and a pulse line output circuit 6 which outputs a plurality of pulse line voltages applied to the primary winding 5a thereof. One end of the secondary winding 5b of the winding transformer 5 is connected to the discharge pin 2, and the other end is connected to the opposite electrode 15. In addition, in the first drawing, one discharge needle 2 and the opposite electrode 15 are shown. However, as described in the previous example (sixth diagram), a plurality of discharge needles 2 arranged for one counter electrode may be configured. A high voltage cable or the like is connected to Q at one end of the secondary winding 5b.

The second series circuit 12' configured by the switching element 10 and the DC power supply 9 200922063 14 to which the DC voltage is applied to the parallel circuit 13 formed by connecting the series circuits 11 and 12 are formed. - and 4: Γ° semiconductor switching elements. This embodiment is composed of two elements FETs. Then, each switch 4, according to Zhao (the fourth) between the input part of the tiger is connected to the control circuit number), controllable: each: road: 7 provides the control signal (on, off the conduction of the letter, ^ 1G Turning on and off (source, drain, yes, = 2 can be formed by switching the transistor to form each switching element 7~.

The present embodiment relates to the output from the pulse line. The voltage of the lead-out portion 'Ua-, 12a of the circuit 6 applied to the primary winding 5a of the winding transformer 5 is the polarity of the electric house of the other output portion of the n-square output portion Ua, which is defined as a positive potential, The polarity of the voltage at the positive side of the other side of the output portion is defined as the voltage of the negative polarity. In this case, in the present embodiment, when the voltage of the positive polarity is applied to the primary winding 5a, the secondary winding is applied. On the side of the discharge electrode 2, a positive voltage is generated on the side of the discharge electrode 2, and when a voltage of a negative polarity is applied to the primary winding 5a, a high voltage of a negative polarity is formed on the side of the secondary discharge electrode 2 at the secondary winding = 5b. CPU, RAM, R by the Binlu icon In the present embodiment, the control circuit 4 outputs an ON/OFF signal (rectangular wave signal) to each according to a program that is previously stored in the ROJV and a data that is previously rotated from the outside. The gates of the switching elements 7 to 1 are turned on and off by the on/off signals, and the switching elements 7 to 1 are turned on and off. Next, the high voltage power supply circuit 3 will be described with reference to the second diagram. The second diagram illustrates the relationship between the on/off control of each of the switching elements 7 to 10 and the voltage (high voltage) generated on the secondary winding 5b of the winding transformer 5 in accordance therewith. 11 200922063 In the present embodiment, in the case where a high voltage of positive polarity occurs on the secondary winding 5 b of the winding transformer 5, during the period TP in the second figure, as exemplified, the first switching element 7 is turned on, and the second is turned off. In the state of the switching element 8 and the third switching element 9, the fourth switching element 1 is turned on and off at a relatively high speed. At this time, in a state where the fourth switching element 10 is turned on, a voltage value having substantially the same magnitude as the output voltage of the DC power source 14 occurs between the output portions 11a and 12a, and has a continuous value with the fourth switching element 10 The positive pulse voltage (rectangular wave pulse voltage) of the pulse width which is substantially equal to the on time (on time) is applied to the primary winding 5a of the winding transformer 5. Therefore, during the period TP in the figure, by repeating the turn-on and turn-off of the fourth switching element 1〇, the voltage of the same waveform as the waveform 20 is turned on and off, that is, the pulse voltage of the plurality of positive polarity is arranged in time series. The positive-electrode-side pulse line ' configured from the output portions 11a and 12a is applied to the primary winding 5a. At this time, in the period TP (hereinafter referred to as the positive side pulse line output period TP), the timing at which the fourth switching element 10 is turned on (the timing of occurrence of each pulse voltage of the positive electrode side pulse line) is appropriately set in advance, And the on-time of the fourth switching element 10 (the pulse width of each pulse voltage of the positive-side pulse line) can be generated on the secondary winding 5b of the winding transformer 5 as shown in the lowermost diagram of the second figure. Pulsed (convex) high voltage VP. More specifically, in the present embodiment, the on/off waveform 20 of the fourth switching element 10 in the positive side pulse line output period TP is turned on, the first half is turned on, the off waveform 20a is turned on, and the second half is turned on and off. 2〇b constitutes. Then, in the positive-side pulse line in the positive-electrode-side pulse line output period TP, the portion corresponding to the first half-side ON/OFF waveform 20a (hereinafter referred to as the positive side pulse: 12 200922063 "lit portion) has a predetermined positive polarity. The timing of the occurrence of the high voltage vp, the function of the fish in the positive vp wave p value (peak). In other words, the start timing of the first half of the pulse line (the start of the first half side and the start of the break wave a) becomes the rising timing of the high voltage vp of the positive polarity, and therefore, by making the first half of the iL_pulse line The start timing change of the portion, as exemplified by the reference symbol vp in the second figure, can cause the occurrence of the high voltage of the positive polarity to deteriorate. Further, by changing the pulse width of any one of the pulse voltages in the front half of the positive-side pulse line, the sum of the pulse widths of the pulse voltages of the positive-side pulse lines (the total of the first half-side turn-on and turn-off waveforms) The on-time change "in the range where the magnetic core of the winding transformer 5 does not generate magnetic flux saturation, as exemplified in the second drawing, the reference symbol νρ, as exemplified, can change the peak value of the high voltage of the positive polarity. At this time, basically, the longer the total pulse width of each pulse voltage of the pulse line on the positive electrode side, the more the peak value of the high voltage of the positive polarity increases. Further, in the positive-side pulse line, the portion corresponding to the second half of the turn-on and off-wave G-shape 2〇b (hereinafter referred to as the second-half portion of the positive-side pulse line) has a high voltage VP preventing the positive polarity from decreasing from the peak value to After 〇[v], a function of a negative counter electromotive voltage is generated on the secondary winding 5b. That is, it is possible to prevent a process in which the high voltage VP from the positive polarity is lowered from the peak to 〇[v], and in the vicinity of 〇[v]., one or a plurality of positive polarity pulses are applied from the output portions 11a, 12a. The voltage is applied to the primary winding 5a, and a negative back-EM voltage is generated on the secondary winding 5b. Further, in the present embodiment, when a high voltage of a negative polarity is generated in the secondary winding 5b of the winding transformer 5, during the period in the figure, as shown in the figure, 13 200922063 is turned on at the third switching element 9, the first switch When the element 7 and the fourth switching element are disconnected, the second switching element 8 is turned on at a relatively high speed, and the sweat is turned on, and only when the second switching element 8 is turned on, at the output = Between 11a and 12a, a negative pulse having a pulse width substantially equal to the output voltage of the DC power source 14 and having a pulse width substantially equal to the ON time of the second switching element 8 (rectangular wave shape) This is applied to the primary winding 5a of the winding repeater 5. Therefore, during the period TN′, the second switching element 8 is turned on and off, and the two parts na and 12a are applied with the same waveform voltage as the on/off waveform 21, that is, the pulse of the plurality of negative polarity. The dust is formed by the dust to the primary winding 5a. No. (4) (hereinafter referred to as the negative pulse side pulse line output period [box Γ aptly sets the timing of occurrence of each pulse voltage of the sequence of the second _ element 8 turned on), and the second switching element is wound ( (4) The pulse width of each pulse voltage of the side pulse line), which can be 之一^5 on one of the human-level windings, as shown in the lowermost diagram of the second figure "I-negative negative pulse-like (convex shape) high voltage In the present embodiment, the positive electrode side pulse line output period 叮:: gate type 'in the negative side pulse line output period tn, the member 8 is turned on and off the waveform 21 is: the first 2a and the second half are connected Turning on and off waveform 21b == skin shape _ row negative period pulse T in the TN period == = =; lower 'called _ ' 4 gauge 疋 negative polarity 〒 voltage VN occurrence timing, and negative 14 200922063 The south of the polarity is the function of the peak value of N (♦ value) of VN. That is, since the start timing of the pulse line half of the negative side becomes the rising timing of the high polarity wide VN of the negative polarity, 闵+ , 匕' The timing of the start of the first half of the pulse line of the negative side is changed as described in the first section - the reference symbol VN For example, it is possible to change the timing of the voltage between the negative and negative electrodes. In addition, the negative electrode is inverted by changing the pulse width of one of the first half of the pulse line of the negative electrode side with w - and the upper pulse voltage. In the range of the saturation of the magnetic flux beam, the sum of the pulse widths of the pulse voltages (the total on-time in the first half-side turn-on and turn-off waveforms) changes, and the core of the winding transformer 5 does not exist - as shown in the second figure. In the middle note, the reference symbol VN, 'exemplified, can change the peak value of the high voltage of the negative polarity. At this time, basically, the longer the pulse width of each pulse voltage of the negative side pulse line, the higher the voltage of the negative voltage. The peak size (absolute % value) increases. * In the ion generating device of the material form, the control circuits 4 are mutually alternately executed from the same period: as described above, the positive side pulse line output period ΤΙ >, to turn on the seventh open ' The element 7, the second switching element 8 and the third switching element 9 are turned off, and the way in which the fourth switching element 10 is turned on and off is repeated, and the switching elements 7 to 10 are turned on and off. Positive side pulse line output control; and as described above During the pole side pulse line output period, the third gate-off element 9 is turned on, the first switching element 7 and the fourth switching element 1 are turned off, and the second switching element 8 is turned on and off. In the embodiment, the negative-side pulse line output protection of the switching elements 7 to 10 is turned on and off. In addition, in the present embodiment, during the positive-side pulse line rounding _τρ and the negative side pulse line output period During the period, as shown in the second figure, the first switching element 7 and the third switching element 9 are controlled to be turned on, and the 15th, 200922063 switching element 8 and the fourth switching element 10 are controlled to be turned off. The figure shows an example of a waveform of a high voltage (alternating high voltage) which occurs in the secondary winding 5b of the winding transformer 5 when the switching elements 8 to 10 are turned on and off. As shown in the figure, on the secondary winding 5b, a positive high voltage VP and a negative high voltage VN alternately occur at a certain period Ta. Then, the high voltage thus generated is applied from the secondary winding 5b between the discharge electrode 2 and the opposite electrode 15. At this time, the period Ta of the present embodiment is a predetermined period of time, which is 5 m seconds (200 Hz in terms of frequency). Then, it is possible to input from the outside: the start timing of the positive-side pulse line output control in the respective periods Ta of the positive polarity high voltage VP (the rising timing of the positive voltage high voltage VP) and the start timing of the negative-side pulse line output control The time interval Tb (hereinafter referred to as the positive-negative time Tb) between the (the rising timing of the negative voltage high voltage VN); the on/off waveform of the fourth switching element 10 in the positive-side pulse line output control is specified. The data of the pattern of 20; and the data of the pattern of the on/off waveform 21 of the second switching element 8 in the negative side pulse line output control are specified to the control circuit 4.

In the second embodiment, in order to detect the micro-discharge which occurs due to the decrease in the discharge h, the power supply is interrupted and the processing of 18 200922063 or the like is performed, and the following PD detecting device is provided. That is, the micro-discharge detecting means in the embodiment of the first embodiment includes the resistor 16 connected to the other end of the secondary winding 5b of the winding transformer 5 of the first figure, and the PD detecting means 30 shown in the fourth figure. A high-pass filter 31 for inputting a PD detection signal taken out from one end of the resistor 16 and inputting its output (high-frequency signal) to generate a one-shot timing of a square wave having a specific time width (for example, 2 (^sec) And a one-shot timer 32; and a microcomputer 33 that inputs a square wave signal output from the timer, and outputs a specific alarm signal according to the determination of the micro-discharge. The PD detecting device 30 is configured according to the PD detection signal. The micro-discharge determination means for outputting an alarm and outputting an alarm and other necessary signals. The fifth diagram shows the circuit configuration of the high-pass filter 31 and the one-shot timer 32 in the PD detecting means 30. The high-pass filter 31 is connected by: a specific capacitor C1 input to the input end of the PD detection signal and a resistor R1 to which the DC voltage Vcc is applied, and output a high frequency signal of a frequency (range) determined by the capacitance and the resistance value thereof The one-shot timer 32 has a transistor Q1 that connects the base at the input end, a DC voltage Vcc on the emitter side, a resistor R2 that is connected between the collector side and the ground, and a collector side of the transistor Q1. Connect the resistor R3 at one end; connect the base at the other end of the resistor R3, and connect the transistor Q2 with the emitter grounded to the collector, and apply the resistor R4 of the DC voltage Vcc; continue to the transistor Q2 and the resistor R4. a capacitor C2 between the connection point and the ground; and sequentially inverting the two inverters II and 12 of the voltage 19 200922063 at the junction of the resistor R4 and the capacitor C2. Next, the implementation of the PD detecting device 30 will be described. In the configuration of the first diagram, a high voltage output from the secondary side of the winding transformer 5 is applied between the discharge needle 2 constituting the discharge electrode and the opposite electrode 15 to generate a corona discharge, such as In the above, micro-discharge occurs due to a decrease in the insulation of the discharge electrode. At this time, the current of the micro-discharge flows from the secondary winding 5b of the winding transformer 5 into the resistor 16. At this time, the voltage detected at one end of the resistor 16 is mainly pulse a high frequency signal of 2 to 1 Onsec (nanosecond), as shown in the sixth (A) diagram, PD of a peak waveform of an alternating high voltage (third diagram) occurring on the secondary winding 5b of the winding transformer 5 The detection signal is input to the input portion of the high-pass filter 31 shown in the fifth diagram (A). The high-pass filter 31 generates a PD detection signal by the filter composed of the above R1 and C1 as the sixth (B) diagram. The high frequency signal is input to the one-shot timer 32, as shown in the sixth (C) diagram, to form a square wave having a time width (eg, 2 (^sec)) detectable by the microcomputer (CPU) 33. Waveform. In detail, in the one-shot timer 32 shown in FIG. 5, when the signal (B) is input to the high level (H), the transistor Q1 is turned off, so the voltage of the resistor R2 is low due to the resistance R3. The base voltage of the connected transistor Q2 is also low, so the transistor Q2 is also turned off. Therefore, the capacitor C2 is charged via the resistor R4 to which the DC voltage Vcc is applied, and the voltage signal at the junction of the resistor R4 and the capacitor C2 is Η. The voltage signal is sequentially inverted by the two inverters II and 12, and is output as a pulse signal of a specific 20 200922063 time width shown in the sixth (C) diagram, and is input to the CPU 33. Further, when the input signal (B) is at a low level (L and 0), the transistor Q1 is turned on, and therefore the voltage of the resistor R2 is high (and Vcc), since it is applied to the base of the transistor Q2 via the resistor R3, The transistor Q2 is also disconnected. Therefore, the capacitor C2 is discharged, and the voltage signal at the junction of the resistor R4 and the capacitor C2 is L. As described above, the CPU 33 counts the number of pulses output from the one-shot timer 32, and determines that it is micro-discharge when it exceeds a predetermined number (e.g., the number per one second). As a result, the power supply to the power supply circuit 3 is interrupted from the CPU 33. The supplied signal is sent to the control circuit 4 of the first figure, and an alarm signal for turning it on or off is transmitted to the front surface of the casing of the ion generating apparatus. An alarm display 34 such as a configured LED. By this processing, that is, the interruption of the power supply, it is possible to prevent the power supply circuit 3 and the ion generator main body from being ignited or burnt, and the insulation display is notified by the alarm display that the insulation of the discharge electrode is lowered, and the adhesion to the periphery of the electrode is urged. Carbon and dirt. The micro-discharge detecting means of the above embodiment is a current flowing through the resistor 16 connected to the ground side of the secondary winding 5b of the winding transformer 5 as shown in "PD detection (1)" in the first figure. The side output return current) is used to detect the micro discharge, but it can also be detected from the discharge pin side output of the winding transformer 5 as shown in the "PD detection (2)" in the first figure. In addition, the current generated by the micro-discharge is generated on the secondary side of the transformer. However, the primary side also generates the same current waveform by mutual induction of the transformer, and thus may also be from the primary side of the winding transformer 5. For testing. The seventh figure shows the pulse line from the primary side of the winding transformer 5. 200922063 The implementation state of the DC power supply side or the ground side of the output circuit 6 when the micro discharge is detected. As shown in the seventh figure, when detecting from the ground side of the pulse line output circuit 6, the resistor 35 is connected between the connection points of the two switching elements 8 and 10 on the ground side and the ground. Then, as indicated by "PD detection (3)", the PD detection signal is taken out from its connection point b. In addition, when the DC power supply (regulated voltage source Vcc) side of the pulse line output circuit 6 is detected, as shown in "PD detection (4)", the connection point of the two switching elements 7 and 9 from the DC power supply side is a. Remove the PD detection signal. In the above embodiment, the high-voltage power supply circuit is configured to have a bypass circuit. However, the configuration is not limited to the bypass circuit, and any high-voltage power supply can be used to output a necessary high voltage to the discharge electrode. In addition, the voltage applied to the primary side of the winding transformer can be either DC or AC, and the high voltage output from the secondary side can also be DC or AC. As shown in the eighth (Α) diagram, a power supply circuit may be constructed by connecting an alternating current power source (e.g., commercial frequency power source) 36 to the primary winding 5a of the winding transformer 5 and applying an alternating voltage to the primary side. At this time, the resistor 37 is connected to the ground side of the primary winding 5a, and the PD detection signal is taken out from the connection point c thereof. Alternatively, the PD detection signal may be taken out from the point d on the non-ground side of the primary winding 5a. Further, when the micro discharge is detected from the secondary side of the winding transformer 5, the resistor 38 is connected to the ground side of the secondary winding 5b of the winding transformer 5, and the PD detection signal is taken out from the connection point e thereof. Alternatively, it may be detected from a point f on the non-ground side of the secondary winding 5b. Furthermore, as shown in the eighth (B) diagram, it is also possible to apply a DC voltage regulator Vcc to one end of the primary winding 5a of the winding transformer 5, and connect the sustaining circuit 22 at the other end 22 200922063 to the circuit 39 to apply the clock on the primary side. The alternating high frequency voltage of the signal. Then, the secondary winding 5b is connected to the DC high voltage output circuit 40 of the high voltage generating circuit, and the power supply circuit is formed by outputting a DC high voltage from the secondary side. At this time, the PD detection signal can also be taken out from either the voltage regulation side of the primary winding 5a or the oscillation circuit side. Alternatively, the resistor 38 may be connected to the ground side of the secondary winding 5b, the PD detection signal may be taken out from its connection point, or the PD may be taken out from the non-ground side of the secondary winding 5b or the output of the DC high voltage output circuit 40. Detection signal. In the previous example shown in the ninth diagram, the power supply circuit 41 is composed of a surge circuit 51 that generates a parent current south frequency voltage by applying a direct current voltage, and a winding transformer 52 that boosts the generated alternating high frequency voltage. . The oscillating circuit 51 is connected to the commercial power source 54 via the DC power supply circuit 53, and the winding transformer 52 receives the output of the oscillating circuit 51 with the primary winding, and outputs the high voltage from the output terminal to the high voltage cable by the secondary winding by electromagnetic induction. 42. Alternatively, instead of the winding transformer 52, a piezoelectric transformer composed of piezoelectric ceramics may be used to boost the high-frequency voltage. In any of the above configurations, as in the eighth (A) diagram or the eighth (B) diagram, the PD detection signal can be taken out from either the primary side or the secondary side of the winding transformer 52.
