本考案はテレビジョン受像機等に使用される直流高圧発
生装置に関するものである。[Detailed Description of the Invention] The present invention relates to a DC high voltage generator used in television receivers and the like.
第１図は従来の高圧コイル３分割型の直流高圧発生装置
の電気的結線図、第２図はその要部断面図である。FIG. 1 is an electrical wiring diagram of a conventional high voltage coil type DC high voltage generator, and FIG. 2 is a sectional view of the main parts thereof.
第１図、第２図において、１はアース端部、２は磁心、
３は低圧コイル、４ａ、４ｂ。In Figures 1 and 2, 1 is the ground end, 2 is the magnetic core,
3 is a low voltage coil, 4a, 4b.
４ｃはそれぞれ第１の高圧コイル、第２の高圧コイル、
第３の高圧コイルで、５ ａｙ ５ ｂｙ ５ ｃ
はそれぞれ第１のダイオード、第２のダイオード、第３
のダイオード、６は直流高圧出力部である。4c are a first high voltage coil, a second high voltage coil,
With the third high voltage coil, 5 ay 5 by 5 c
are the first diode, the second diode, and the third diode, respectively.
The diode 6 is a DC high voltage output section.
この装置において、アース端部１に先ず第１の高圧コイ
ル４ａを接続腰次に第１のダイオード５ａを接続し、次
に第２の高圧コイル４ｂを順次接続し、最後に第３のダ
イオード５ｃを接続して、そのカソードが直流高圧出力
部６に接続された結線となっている。In this device, first the first high voltage coil 4a is connected to the ground end 1, then the first diode 5a is connected, then the second high voltage coil 4b is connected in sequence, and finally the third diode 5c is connected. is connected, and its cathode is connected to the DC high voltage output section 6.
すなわち、従来装置では、高圧コイル４ｂ、４ｃがダイ
オード５ａｔ５ｂｔ５０により挾された構造になってい
るため、テレビの水平走行期間において、これら高圧コ
イル４ｂ、４ｃがアースから浮いた状態となり、アース
に対するコイルの容量は極めて小さくなり、その結果高
次同調動作が可能になる。That is, in the conventional device, the high-voltage coils 4b and 4c are sandwiched between the diodes 5at5bt50, so that during the horizontal running period of the TV, these high-voltage coils 4b and 4c are in a floating state from the ground, and the coils with respect to the ground are The capacitance becomes extremely small, resulting in high order tuning operation.
しかし、各コイルの電気的中性点がコイル共巻線数の１
７２の点よりも低電位側に寄っており、帰線期間に生ず
るフライバックパルスはコイルの低；電位端は小さい負
パルスであり、コイルの高電位端は大きな正パルスを生
じている。However, the electrical neutral point of each coil is equal to the number of co-windings in the coil.
It is closer to the low potential side than point 72, and the flyback pulse generated during the retrace period is a small negative pulse at the low potential end of the coil, and a large positive pulse at the high potential end of the coil.
高圧コイル４ａ、 ４ｂｔ ４ｃの巻数がほぼ等し
い場合の高圧コイル各部の電圧波形の実測値の一例を第
６図に示す。FIG. 6 shows an example of actual measured values of voltage waveforms at various parts of the high-voltage coils when the number of turns of the high-voltage coils 4a, 4bt 4c is approximately equal.
ブラウン管への電気エネルギーの供給はこの１正パルス
のピーク付近のダイオードの導通で行われるが、正パル
スのパルス高が高い場合、ピーク付近のパルス幅が狭く
なり、ダイオード導通期間が短い。Electrical energy is supplied to the cathode ray tube by conduction of a diode near the peak of this one positive pulse, but when the pulse height of the positive pulse is high, the pulse width near the peak becomes narrow and the diode conduction period is short.
さらに高圧コイル４ａは一端がアース点につながってお
り、そのため同調矢数も低い。Furthermore, one end of the high voltage coil 4a is connected to the ground point, and therefore the number of tuning arrows is low.
このような回路構成はエネルギー供給上不利であり、そ
の結果、高圧変動率も大となる。Such a circuit configuration is disadvantageous in terms of energy supply, and as a result, the high voltage fluctuation rate is also large.
上記のように、従来の直流高圧発生装置はブラウン管ビ
ーム電流の変動に対する高圧の変動が大であった。As mentioned above, in the conventional DC high voltage generator, the high voltage fluctuates greatly in response to fluctuations in the cathode ray tube beam current.
本考案の目的は、上記したブラウン管ビーム電流の変動
に対する高圧変動率を小さくするようにた直流高圧発生
装置を提供することにある。An object of the present invention is to provide a DC high voltage generator that reduces the rate of high voltage fluctuation with respect to the above-mentioned fluctuations in the cathode ray tube beam current.
本考案は、高圧コイルをダイオードにより複数にほぼ等
分割し、また高圧コイルとダイオードの接続配置におい
て、ダイオードと高圧コイルの接続順序を、最も低圧側
には先ずダイオードを接続し、次に高圧コイルという順
序で接続し、最終段は高圧コイルで、その巻き終りをダ
イオードを介さずに負荷に導くようにしたものである。The present invention divides the high voltage coil into multiple parts using diodes, and also connects the high voltage coil to the diode in the order in which the diode and high voltage coil are connected.The diode is connected to the lowest voltage side first, and then the high voltage coil is connected to the high voltage coil. The final stage is a high-voltage coil, and the end of the winding is led to the load without going through a diode.
本考案の１実例を高圧コイルを３段分割した場合につい
て説明する。An example of the present invention will be described in which a high voltage coil is divided into three stages.
第３図は本考案の一実施例の電気的結線図、４図はその
要部断面図である。FIG. 3 is an electrical wiring diagram of an embodiment of the present invention, and FIG. 4 is a sectional view of the main part thereof.
第３図、第４図の各部に付した記号は第１図、第２図の
各記号に対応する。The symbols attached to each part in FIGS. 3 and 4 correspond to the symbols in FIGS. 1 and 2.
この装置において、アース端部１に先ず第１のダイオー
ド５ａを接続し、次に第１の高圧コイル４ａを接続し、
次に第２のダイオード５ｂを順次接続し、最後に第３の
高圧コイル４Ｃを接続して、その高電位端をブラウン管
アノードに導接した結線となっている。In this device, first a first diode 5a is connected to the ground end 1, then a first high voltage coil 4a is connected,
Next, the second diode 5b is connected in sequence, and finally the third high voltage coil 4C is connected, and the high potential end thereof is connected to the cathode ray tube anode.
このように、高圧コイル４ａ、４ｂがダイオード５ａ、
５ｂ、５ｃて挾まれた構造になっているため、これらコ
イルは高次同調が可能である。In this way, the high voltage coils 4a, 4b are connected to the diodes 5a,
Because of the structure in which coils 5b and 5c are sandwiched, high-order tuning is possible for these coils.
高圧コイル４Ｃの出力側にはダイオードが接続されてな
く、高抵抗を介してアースに接地された状態となってお
り、高次同調の面からは高圧コイル４Ｃのき終り端にダ
イオードを取り付けた場合より不利である。There is no diode connected to the output side of the high-voltage coil 4C, and it is grounded to the ground via a high resistance.From the standpoint of high-order tuning, a diode is attached to the end of the high-voltage coil 4C. It is more disadvantageous than the case.
しかし、高圧コイル４ｃの高電位端は直流電位であるの
で、高圧コイル４ｂの電気的中性点、高圧コイル４ａの
電気的中性点が、それぞれコイルの１７２の巻数の点よ
りも高電位側に寄り、その結果、高圧コイルが発生する
正のパルス高が負のパルス高よりも低く、正のパルスの
ピーク点付近のパルス幅が従来よりも広くなり、ブラウ
ン管にエネルギーを供給する上で有利となる。However, since the high potential end of the high voltage coil 4c is at DC potential, the electrical neutral point of the high voltage coil 4b and the electrical neutral point of the high voltage coil 4a are on the higher potential side than the 172 turns point of the coil. As a result, the positive pulse height generated by the high-voltage coil is lower than the negative pulse height, and the pulse width near the peak point of the positive pulse is wider than before, which is advantageous in supplying energy to the cathode ray tube. becomes.
その結果、高圧変動率も小さくなる。As a result, the high pressure fluctuation rate is also reduced.
高圧コイル４ａ、４ｂ、４ｃの巻数がほぼ等しい場合の
高圧コイル各部の電圧波形の実測値の−・例を第７図に
示す。FIG. 7 shows an example of actual measured values of voltage waveforms at various parts of the high-voltage coils when the number of turns of the high-voltage coils 4a, 4b, and 4c is approximately equal.
第５図に従来直流高圧発生装置と本考案直流高圧発生装
置の高圧変動特性の一例を示す。FIG. 5 shows an example of the high pressure fluctuation characteristics of the conventional DC high pressure generator and the DC high pressure generator of the present invention.
図中の曲線ａは従来装置の場合、曲線すは本考案装置の
場合である。Curve a in the figure is for the conventional device, and curve 2 is for the device of the present invention.
図よりオ）かるように、ブラウン管負荷電流Ｏ〜１ｍＡ
の変動に対し、従来装置では高圧が約１１％変動したが
、本実例では約７％の変動となり高圧変動率が約４％改
善されるに至った。As shown in the figure, the cathode ray tube load current is O~1mA.
With respect to the fluctuation of , the high pressure fluctuated by about 11% in the conventional device, but in this example, it fluctuated by about 7%, resulting in an improvement in the high pressure fluctuation rate by about 4%.
以上は高圧コイルをダイオードで３段分割した場合につ
いて説明したが、３段分割以外の複数段分割の場合及び
各高圧コイルを分割するダイオードを数個使用した場合
でも同様の効果が得られるのは明らかである。The above explanation is about the case where the high-voltage coil is divided into three stages using diodes, but the same effect can be obtained even when the high-voltage coil is divided into three stages other than three stages, or when several diodes are used to divide each high-voltage coil. it is obvious.
