Claims (1)
チヨツパ回路を接続し、高調波低減型整流回路の
動作に降圧チヨツパ回路の動作を同期させること
により、交流入力の力率を約１．０に保ち、かつ
出力電圧を可変に制御可能な交流直流変換装置。 In a harmonic-reducing rectifier circuit, a step-down chopper circuit is connected to the output terminal, and the operation of the step-down chopper circuit is synchronized with the operation of the harmonic-reducing rectifier circuit, thereby maintaining the power factor of the AC input at approximately 1.0. , and an AC/DC converter that can variably control the output voltage.
