がら、このように電源周波数で直接駆動させると、変圧
器が大型・重量化し、製造コストも高くなるという欠点
があった。とくに、容量の大きな変圧器はど、それは顕
著であった。。Traditionally, transformers operate at a commercial frequency of 50Hz (or 60Hz
) was connected directly to the power supply. However, such direct driving at the power supply frequency has the disadvantage that the transformer becomes larger and heavier, and the manufacturing cost becomes higher. This was especially true for transformers with large capacities. .
本発明の目的は、上記従来の技術の欠点を克服し、小型

駆動回路を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a transformer drive circuit that overcomes the drawbacks of the above-mentioned conventional techniques and enables a transformer that is small, lightweight, and inexpensive to manufacture.
以下、図によって本発明を具体的に説明する。Hereinafter, the present invention will be specifically explained with reference to the drawings.
第１図は、本発明の第一実施例からなる変圧器の駆動回
路の回路図である。FIG. 1 is a circuit diagram of a transformer drive circuit according to a first embodiment of the present invention.
■は交流電源（５０Ｈｚまたは６０１ｋ） 、２は変圧
器の駆動回路、３が変圧器および４が負荷である。2 is an AC power supply (50Hz or 601K), 2 is a transformer drive circuit, 3 is a transformer, and 4 is a load.
変圧器の駆動回路２において、一対の入力端子５および
出力端子６をそれぞれ結ぶ回路７に並列に、まずピーク
検出回路８を設け、その出力を前記回路７に直列に挿入
した一対のスイッチ９Ａ・９Ｂにそれぞれ接続するとと
もに、回路７と並列に設けたインバータｌＯに接続する
。そして、インバータ１０の出力を回路７と並列に設け
た一対のスイッチＩＩＡ・１１Ｂにそれぞれ接続する。In the transformer drive circuit 2, a peak detection circuit 8 is first provided in parallel with a circuit 7 that connects a pair of input terminals 5 and an output terminal 6, and the output of the peak detection circuit 8 is inserted in series with the circuit 7. 9B, and also connected to an inverter IO provided in parallel with the circuit 7. Then, the output of the inverter 10 is connected to a pair of switches IIA and 11B provided in parallel with the circuit 7, respectively.
ただし、スイッチＩＩＡの入力側はスイッチ９Ａの入力
側に、およびスイッチＩＩＡの出力側はスイッチ９Ｂの
出力側に接続され、スイッチ１１Ｂの入力側はスイッチ
９Ｂの入力側に、およびスイッチＩＩＢの出力側はスイ
ッチ９Ａの出力側に接続されている。However, the input side of switch IIA is connected to the input side of switch 9A, the output side of switch IIA is connected to the output side of switch 9B, the input side of switch 11B is connected to the input side of switch 9B, and the output side of switch IIB. is connected to the output side of switch 9A.
すなわち、スイッチ９ＡとスイッチＩＩＢ、およびスイ
ッチ９ＢとスイッチＩＩＡとをこのように接続すること
により、入力端子５の電圧はピーク検出回路８の出力と
インバータ１０の出力とにより、半周期毎に交互に出力
端子６に現われるようになるのである。That is, by connecting switch 9A and switch IIB, and switch 9B and switch IIA in this way, the voltage at input terminal 5 is alternately changed every half cycle by the output of peak detection circuit 8 and the output of inverter 10. It will appear at the output terminal 6.
その様子を第２図を用いて説明する。The situation will be explained using FIG. 2.
（Ａ）は入力端子５の電圧（電源電圧）波形、（Ｂ）は
ピーク検出回路８の出力電圧（電源電圧の正のピークも

ピーク検出回路８の出力電圧と逆の波形）、および（Ｄ
）は出力端子６の電圧（変圧器３の入力電圧）波形であ
る。(A) is the voltage (power supply voltage) waveform of the input terminal 5, (B) is the output voltage waveform of the peak detection circuit 8 (rises at or near the positive peak of the power supply voltage, falls at or near the negative peak) , (C) is the output waveform of the inverter lO (
waveform opposite to the output voltage of the peak detection circuit 8), and (D
) is the voltage waveform of the output terminal 6 (the input voltage of the transformer 3).
なお、スイッチ９Ａ・９ＢとスイッチＩＩＡ・１１Ｂと
は互いに逆の動作をし、ピーク検出回路８の出力電圧の
立上り時（インバータｌＯの出力電圧の立下り時）には
スイッチ９Ａ・９Ｂはｏｆｆ、スイッチＩＩＡ・ＩＩＢ

時（インバータｌＯの出力電圧の立上り時）にはスイッ
チ９Ａ・９ＢはＯｎ％スイッチＩＩＡ−１１８はｏｆｆ
となる。Note that the switches 9A and 9B and the switches IIA and 11B operate in opposite directions, and when the output voltage of the peak detection circuit 8 rises (when the output voltage of the inverter IO falls), the switches 9A and 9B are turned off. Switch IIA/IIB
is turned on, and when the output voltage of peak detection circuit 8 falls (when the output voltage of inverter lO rises), switches 9A and 9B are turned on, and switch IIA-118 is turned off.
becomes.
すなわち、ピーク検出回路８の出力（Ｂ）が現われてい
る半周期には入力電圧（Ａ）の波形が逆転して出力電圧
（Ｄ）に現われ、インバータ１０の出力（Ｃ）が現われ
ている半周期には入力電圧（Ａ）の波形がそのまま出力
電圧（Ｄ）に現われる。That is, during the half period when the output (B) of the peak detection circuit 8 appears, the waveform of the input voltage (A) is reversed and appears as the output voltage (D), and during the half period when the output (C) of the inverter 10 appears. During the period, the waveform of the input voltage (A) appears as it is in the output voltage (D).
したがって、入力電圧（電源電圧）（Ａ）に比べて出力
電圧（変圧器の入力電圧）（Ｄ）は、周波数が２倍とな
る。Therefore, the frequency of the output voltage (transformer input voltage) (D) is twice that of the input voltage (power supply voltage) (A).
このように、変圧器３に印加される電圧の周波数が、電
源周波数すなわち従来直接印加されていた周波数の２倍
になると、次式から説明されるように変圧器３の磁路断
面積が％で済むため、変圧器３は小型化され、軽量にな
り、製造コストも低減する。In this way, when the frequency of the voltage applied to the transformer 3 becomes twice the power supply frequency, that is, the frequency that was conventionally applied directly, the magnetic path cross-sectional area of the transformer 3 becomes % as explained by the following equation. Therefore, the transformer 3 can be made smaller and lighter, and the manufacturing cost can also be reduced.
いま、変圧器に印加される電圧の実効値をＥ（Ｖ）とす

ただし、Ｋ＝Ｅ／ ４．４４Ｎ＋ ｘ １０（ｆ：印加
周波数（Ｈｚ） 、ＮＩ ： １次巻数、Ａｉ：実効磁
路断面積〔−〕）
で表わされる。したがって、周波数が従来の２倍になれ
ば、磁路断面積は従来の２で済む。Now, if the effective value of the voltage applied to the transformer is E (V), the maximum magnetic flux density Bm (Wb/-) of the transformer is: Bm=E/ 4.44 f N1A i X 10-8
= to/fAi 8 However, K=E/ 4.44N+ x 10 (f: applied frequency (Hz), NI: number of primary turns, Ai: effective magnetic path cross-sectional area [-]). Therefore, if the frequency is twice that of the conventional one, the magnetic path cross-sectional area will only need to be two compared to the conventional one.
なお、ピーク検出回路８の出力を交互にスイッチングす
