Description
図1において、商用電源11から供給される交流電圧を、駆動用のスイッチSW、コンバータ12を介して直流電圧に変換する。コンバータ12から供給される直流電圧に基づいてインバータ13で高周波を生成する。
図2において、電源11の交流電圧は、直流電源121,122それぞれのトランスT1の1次コイルLaに供給する。トランスT1の2次コイルLbから取り出される巻線比に応じた交流電圧を生成する。それぞれのトランスT1の2次コイルに導出された交流電圧は、整流用のダイオードD1、コンデンサC1で平滑されて直流電圧に変換される。直流電源121,122から出力される直流電圧は、加算されてコンバータ12の出力としてインバータ13の駆動用電源として供給する。
