"The symbol" is shown in the figure. Figure 1 shows the configuration of the device. The i-th diagram and the spear-phase circuit are respectively inserted in the commercial AC power supply and the second to the second to the third to the 321569 4 201044756 'nth rectifier circuit Between Ri and Rn-i. Fig. 1 shows a state in which the output lines of the first to nth*th rectifying circuits R0 to Rn_i are connected in parallel to drive a load, and Fig. 2 shows the first to nth rectifying circuits to The output line of Rn-1 is connected in series to drive the state of the load. • If the drive for the load is configured in this way, the pulse flows whose phases are deviated from each other are output from the first to nth rectifying circuits R〇 to Rn_i. Two terminals that are connected or connected in parallel and supplied to the load. Since the output waveform of the rectifier circuit is set to a phase difference with respect to the output waveform of the other rectifier circuit, the waveform of the combined wave is the peak of the pulse flow. The troughs are heavy and stacked, and the result is a high-frequency component having a high fundamental frequency (for example, a commercial frequency AC E of 60 Hz and a fundamental frequency of 120 Hz). Therefore, voltage fluctuation applied to the load can be suppressed. And current change For example, a configuration example of the phase shifting circuit can be configured as a power line on the first side (hot side L) and the second side (cold side N) of the commercial alternating current power source E and at least (η·1) A capacitor 〇 element is inserted between each of the input lines of the rectifier circuit. In this case, the number of capacitor elements is 2 (η-1) in total. From the first rectifier circuit R〇, ..., the η rectifier circuit The output system in which Rn-i is connected in series or in parallel is symmetrical with respect to the hot side L and the cold side n of the commercial alternating current power source E, that is, even if the hot side L and the cold side N are exchanged, the same configuration is achieved. The variation of the wheel-in voltage and the load fluctuation are affected. The other configuration example of the phase-shifting circuit may be a power line and the first one inserted in either the hot side L or the cold side N of the commercial AC power source E. At least one of the (n_1}th rectifier circuits of the nth rectifier circuit core to Rni is formed by a capacitor element between the lines 5 321569 and 201044756. In this case, the number is total (n_1). From (6) Rectifier circuits in series or in parallel = two (four) output, although not relative to commercial The power supply is Η and symmetrical; the effect of suppressing the continuous wave applied to the load is sufficiently obtained. In this case, the insulation of the remaining side of the η_υ rectifier circuit is insulated from the load by an insulating circuit. Preferably, a transformer is used as an example of the circuit. In addition, in the DC power supply device according to the present invention, it is preferable that the first rectifier circuit R is inserted in the output line of the first choke circuit and the ? The output of the first converter (converter circuit) is shown in Fig. 3 and Fig. 4 as an example of using a converter circuit (4) between the load of the rectifier circuit and the load. It is then possible to apply the desired value to the voltage applied to the load. In addition, in addition to the aforementioned second converter circuit IG, the second rectifier circuit can also be used! The output line of ^ has a conversion second rectifier circuit: the: converter circuit operator "'..; on the first side... enters the nth converter circuit U with the output of the conversion "rectifier circuit R". An example of the circuit configuration is shown in FIGS. 5 and 6. The circuit 2 can be set to a desired value by the adjustment of each converter circuit W U . (Effects of the Invention) According to the present invention, it is possible to suppress chopping applied to a load. In addition, it is not necessary to be evaluated as an electrolytic capacitor having a short life, and it is possible to achieve a long life and miniaturization of the DC power supply 321569 6 201044756. In particular, when it is used for lighting of a led light, it is possible to suppress the flicker of the light of the LED of the lighting to a level that is not known at the time of viewing. The above and other advantages, features, and advantages of the invention will be apparent from the description of the embodiments described herein. [Embodiment] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Fig. 7 and Fig. 8 are diagrams showing a specific circuit configuration of a DC power supply device 10A to which the present invention is applied. The DC power supply unit 10A is a device for driving a load. There is no particular limitation on the load. For example, an LED (light-emitting diode), a discharge tube such as a cold cathode tube, an electronic device such as a personal computer, an electric appliance, or the like can be given. Hereinafter, the case where the load is an LED is explained. The DC power supply device 10A is connected to the commercial AC power supply E. In the "phase shifting circuit" for the parent current power supply having a phase difference P that is 0 degrees ahead of each other (the alternating current period of the alternating current power source is 370 degrees), the 5 series are respectively provided in the commercial alternating current power source E. Capacitor elements q and C2 between the power supply line on the hot side L and the cold side N and the two input lines of the second turn rectifier circuit Ri. With this capacitor element, it is possible to obtain a phase difference of approximately 90 degrees with respect to the power source input to the first rectifier circuit R?. Further, although a "phase shifting circuit" is exemplified as a capacitor belonging to a phase-inducing element, an inductance element belonging to a late-phase element may alternatively be used. The DC power supply device 10A includes a first rectifier circuit R〇 connected to the commercial AC power supply E and rectified the AC power supply to obtain a pulse flow, and the second rectifier circuit Ri is connected via the capacitor elements (^, C2). 7 321569 201044756 The output line of the first rectifier circuit R〇 is inserted into a DC/Dc converter circuit that converts the output of the 1st circuit R.

That is, when the gates of the i switching elements SW1 are turned on (turned off) by the pulse voltage, the dead pixels of the other i switching elements are also turned on (_). The i-th rectified power is turned on by the turn-on and turn-off operations of the two switching elements sw. The pulse output is switched at high frequency. The switching frequency, i.e., the frequency of the gate pulse voltage, is not limited, but is set to about 1 to 2 times the frequency of the commercial AC power supply. A choke coil c m, c Η 2 is used to absorb the frequency component of the switched high frequency current and maintain the current applied to the load. The voltage stepped down by the DC/DC converter circuit is applied to the load LED, and the difference between the voltage of the step-down voltage and the voltage of the commercial AC power source ε is applied to both ends of the capacitor element Ci and the capacitor element C2. end. Fig. 9 (a) and (b) are voltage waveform diagrams of respective nodes a and b of the DC power supply device i 〇 a of Fig. 7, and Fig. 9 (4) is a current waveform diagram of the node c. The ninth rectifying circuit R is shown in Fig. 9 (8). The output node & voltage, which is the pulse output itself. Figure 9(b) shows the voltage at the output node b of the switching element swi, sW2 321569 8 201044756 ', which is the wave shape of the pulse output output switched at high frequency. Fig. 9(c) shows the current flowing from the output node c of the choke coils CHI, CH2 to the load. As shown in Fig. 7, the high-frequency current obtained by the on-off operation of the switching elements SW1, SW2 is accumulated in the choke coils CH1, CH2. Since the choke coils CHI and CH2 absorb high-frequency currents having a frequency of 102 to 104 times the frequency of the commercial AC power source E, a large capacity is not required, and a small size is sufficient. Ο As shown in Fig. 7, the output lines of the two choke coils CHI and CH2 and the output lines of the second rectifying circuit & are connected in parallel with each other. The output line is connected to the two terminals of the load LED. Further, as shown in Fig. 8, the output lines of the two choke coils CHI and CH2 and the output lines of the second rectifying circuit R! may be connected in series to each other. As shown, the output path of the choke coil CH1 and one of the output lines of the second rectifying circuit & are connected to both terminals of the load LED. As described above, the commercial AC system that is rectified by the rectifier circuit and R! rectifies directly into the switching circuits SW1 and SW2 in the form of pulsations and is switched by high frequency, and then passes through the anti-current coils CHI and CH2, which are generally directly pulsed. The form of the flow is supplied to the load LED. Since the AC power source that has entered the second rectifier circuit & passes through the capacitor elements q and C2, the phase is advanced compared with the AC power source that enters the first rectifier circuit R〇. The phase difference p differs depending on the difference between the input voltage and the output voltage, and the larger the difference, the closer the phase difference is to 90 degrees. Further, the material/type of the dielectric material of the capacitor element can be arbitrarily selected from ceramics, paper, and film 9 321569 201044756 and the like. Further, as described above, an inductance element belonging to a late phase element may be used instead of the capacitor element. - The waveforms which are combined in parallel or in series by the above-described method are shown by the solid line and the broken line of Fig. 9), and the peaks and troughs of the pulsating flow overlap each other, and as a result, 疋 contains many frequencies of the pulsating flow ( For example, if the commercial AC power source E is deleted, it means that the frequency component is higher than 2). Therefore, voltage fluctuations and current fluctuations applied to the load LED can be suppressed. In addition, since it is not necessary to use a smoothing circuit having three electrolytic electricity, it is not necessary to use an electrolytic capacitor having a relatively long life, and it is possible to achieve a longer life and a smaller DC power supply device. Fig. 10 shows a seventh drawing A circuit diagram of a DC power supply device 〇B of a modified example of the deformation. In this circuit, the capacitor element q is inserted only between the power supply line of the hot side 1 of the commercial alternating current power supply E and the - input line of the second, current circuit R1. This circuit configuration can also obtain a phase difference p' by the capacitor 7(^), but it becomes asymmetrical from the load, so the chopping component is increased in the synthesized waveform. However, in the circuit of the i-th diagram In the same manner, the effect of the present invention in which the electrolytic capacitor is omitted and the voltage fluctuation or current fluctuation applied to the load can be suppressed. Next, Fig. 11 and Fig. 12 show an improvement of the first drawing. Fig. 11 and Fig. 12 In the DC power supply device 1c, the capacitor element core is inserted only between the power supply line of the hot side L of the commercial AC power supply and the input line of the second rectifier circuit 1. Alternatively, the capacitor element may be used instead of the capacitor element. The inductance element of the phase element. The configuration and connection of the ith rectifier circuit R and the second rectifier circuit R1 are shown in Fig. 7, Fig. 8 and Fig. 7(3). 321569 10 201044756 ' and Fig. 7, Fig. 8, The difference from Fig. 10 is that a transformer T0 having a function as an insulating circuit is connected to the output side of the converter circuit for converting the output of the first rectifier circuit R?, and is on the secondary side of the transformer Τ0. Linked to the rear The flow circuit R' rectifies and supplies the secondary voltage of the transformer 至 to the load. The converter circuit includes: parallel switching elements SW3 and SW4 connected to the two output lines of the first rectifier circuit R〇 for connecting The pulse output is switched at a high frequency that is inverted from each other; and the capacitors C3, C4 are connected to the two ends of the parallel switching elements SW3, SW4. The intermediate point of the series switching elements SW3, SW4 is intermediate with the capacitors C3, C4 The point is connected to the primary winding of the transformer T. The inverted pulse voltage is supplied to the gates of the two switching elements 'SW3 and SW4. As described above, the commercial alternating current is rectified by the first rectifier circuit R〇. Directly enters the switching circuits SW3 and SW4 in the form of pulsating flow, and is switched by high frequency, and then boosted or stepped down by the transformer T〇 to be supplied to the load. Since it is a high-frequency voltage that is processed by the switching process, the transformer is T〇 is a small one, which is also a great advantage. On the other hand, since the AC power entering the rectifier circuit I is via the capacitor element q, compared with the AC power source entering the first rectifier circuit R〇, The phase lead is advanced. As shown in Fig. 11, the phase-leading AC power source and the AC power source supplied from the secondary side of the transformer To are connected in parallel to each other and to both terminals of the load. Further, as shown in Fig. 12, 2 The AC power supplies can also be connected in series with each other and connected to the two terminals of the load. 11 321569 201044756 波形Two-in-one wave pattern, the wave ♦ and wave Γ of the pulse flow (refer to Figure 9 (4)), the result is A frequency component containing a plurality of frequencies higher than the pulse ratio.

In addition, in the circuit configurations of the U and 12, the output side of the first 敕== output side and the second rectification power is used; ["Ground edge, therefore, normal mode noise can be prevented one by one. In the case of e), the i-th rectifying circuit R0 and the second rectifying circuit I block the adverse effect. Therefore, a stable operation can be expected. Further, in the modified example, the eleventh and twelfth drawings may be used. In the lightning path configuration, the capacitor element c is provided on the side of the first rectifier circuit & the phase of the AC power supply of the first rectifier circuit is advanced. 1 The 13th and 14th drawings show that the capacitor rectifier circuit is tired. On the side of 0, the straight m factory is connected to the first circuit command, and the circuit diagram of 10D is set from the complex circuit. Here, the second rectifier circuit is directly applied to the negative 1 positive current circuit. Applied to the load, (4) (that is, the voltage applied by the rhinoceros sigma 1, λ, which is pressed in the capacitor element Ci), the voltage drop is: the load is applied to the load for lifting. The factory is using the step-up transformer to be used as a transformer. In addition, it can also be shown in Figure 13 and Figure 14. :: Add SW5, rectifier diode D, and anti-cutoff. (10) State paste converter circuit. In m16=321569 12 201044756, an example of a circuit is added as described above. • In addition, Fig. 17 Fig. 18 shows a circuit of a DC power supply device iOF using a switching element SW8 instead of the rectifying diode D. A pulse voltage of the same frequency is applied to the gate of the switching element SW5 of the circuit and the gate of the switching element SW8, respectively. Each of the pulse voltages is inverted from each other, and the other gate is turned off when one of the gates is turned on. The gate voltage of the switching element SW5 becomes a ratio of a period of 0 to the on-off period of the on-off period of the pulse (the period during which the gate voltage of the switching element SW5 is turned on) The larger the duratlon, the larger the output voltage of the converter circuit. The larger the ratio of the period during which the gate voltage of the switching element SW8 is turned on relative to the period of the on-off period of the pulse, the larger the converter circuit The smaller the output voltage is, that is, by changing the aforementioned ratio (durati〇n) of the pulse voltage applied to the gates of the switching elements S W5 and S W8 from 1 to %, it is possible to apply to the load. Voltage into In addition, the degree of freedom of the LED can be adjusted. Further, the converter circuit can be additionally provided on the side of the second rectifier circuit & the ith rectifier circuit R 所示 side shown in Fig. 13G and Fig. 14 The transformer T0 and the rectifier circuit R in the subsequent stage have the same circuit as the circuit. Fig. 19 and Fig. 20 show that the parallel switching elements sw6 and SW7 are connected to the two output lines of the second rectifier circuit R! The pulse current outputs are switched to each other, and capacitors C: 6, C7 are connected to the two end points of the parallel switching elements s w6, SW7; the transformer ι; and the rectifier circuit r". Although the embodiments of the present invention have been described so far, it is needless to say that the present invention is not limited to the above embodiments. For example, in the DC/DC converter, a converter such as a Cuk 321569 13 201044756 type or the like can be used in addition to the above-described chopper type converter. Fig. 21 and Fig. 22 show those in which the converter circuit of Figs. 7 and 8 is replaced by a Cuk type circuit. In the converter circuit of the (10) type, the switching element SW9' is inserted in parallel with the two rounds of the output of the first rectifier circuit for switching the pulse output to a high frequency, and the capacitor element C8, C9 ' is inserted into the switching element § Qing both ends of the fish load = 1T holding the diode D, the capacitor element W transmission line is inserted in series (10) electrical state components C8, C9 Output. A high-frequency pulse voltage is supplied to the gate of the switching element SW9. The first rectifier circuit R is turned off by the conduction ii off & day switching operation of the switching element s W9. The pulse L output is switched at high frequency. ^ ^, with the switching frequency, that is, the gate pulse frequency of 〇2 to the absorption of the heart current power supply, and from the first!

On the other hand, the output line from the second rectifier circuit, the pulse, and the pulse line also catches the pulse current. :::: The electric sacrifice position is generated by more than 0 to 9 due to insertion on the primary side of the second rectifier circuit = =rci. The deviation from the degree is due to the smoothing of the current as in the 9th. Circuit t:, there are still features in this circuit, that is, due to the first rectification.
