Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 入力側および出力側の平滑コンデンサを同時 に小型化する。 【構成】 部分共振型コンバータ11,31を負荷41に直列 接続する。第1のFET3にデューティーD=0.5の 駆動信号を供給する発振器42を設ける。また、発振器42 からの出力を反転させて第1のFET23に駆動信号を供 給する反転器43を設ける。 【効果】 電源装置全体の入力電流Iiは、各コンバー タ11,31の入力電流I1,I2を合成したものとなる。 このため、入力電流Iiのリプル成分は少なくなる。ま た、チョークコイル10,30に加わる電圧VL1,VL2 は、出力電圧Voに等しいリプル成分のない波形とな る。 (57) [Summary] [Purpose] To simultaneously reduce the size of the input and output smoothing capacitors. [Configuration] Partial resonance type converters 11 and 31 are connected in series to a load 41. An oscillator 42 that supplies a drive signal with a duty D = 0.5 to the first FET 3 is provided. Also, the oscillator 42 An inverter 43 is provided which inverts the output from and supplies a drive signal to the first FET 23. [Effect] The input current Ii of the entire power supply device is a combination of the input currents I1 and I2 of the converters 11 and 31, respectively. Therefore, the ripple component of the input current Ii decreases. In addition, the voltages VL1, VL2 applied to the choke coils 10, 30 Becomes a waveform having no ripple component equal to the output voltage Vo.
