전력 변환 장치
전력 변환 장치(100)는, 컨버터(3), 인버터(5), 이들을 제어하는 제어 회로(7)를 구비하고 있다. 제어 회로(7)는, 제 1 캐리어파(Scr2)에 기초하여 컨버터(3)를 제어하는 제 1 제어 신호(s3)와, 제 1 캐리어파(Scr2)와 상이한 주파수 및 위상을 갖는 제 2 캐리어파(Scr3)에 기초하여 인버터(5)를 제어하는 제 2 제어 신호(s5)를 생성한다. 제 1 캐리어파(Scr2)의 주파수(fsw2)와 제 2 캐리어파(Scr3)의 주파수(fsw3)는, 컨버터(3)와 인버터(5)의 사이에 접속된 콘덴서(4)의 전류에...

A power conversion device includes a converter, an inverter and a control circuit that controls them. The control circuit generates: first control signals that control the converter, on the basis of a first carrier wave; and second control signals that control the inverter, on the basis of a second carrier wave having a frequency and a phase that are different from those of the first carrier wave. The frequency of the first carrier wave and the frequency of the second carrier wave have a predetermined relationship therebetween based on a current of a capacitor connected in between the converter and the inverter. |
