Abstract

본 발명은 직류전원을 교류로 변환하는 인버터(역변환기)의 제어회로에 있어서 4개의 제어입력을 갖는 8채널 멀티플렉서의 입력측에 계단식 정현파레벨 전압발생회로를, 출력측에 능동필터를 연결하고 제어입력측에는 리셋트 펄스, 16×NHz의 클락펄스 및 업다운 신호인 NHz의 구형파가 입력되는 BCD 업다운카운터로 회로를 구성하여 비반전 입력 Vc로 조정함에 있어서 신호파인 정현파의 진폭의 크기를 용이하게 조정할 수 있는 것이다.The present invention provides a stepped sinusoidal level voltage generation circuit at the input side of an eight-channel multiplexer having four control inputs in a control circuit of an inverter (inverter converter) for converting a DC power source into an alternating current, an active filter connected to the output side, and a control input side It is easy to adjust the amplitude of the sine wave, which is a signal wave, by adjusting the non-inverting input Vc by constructing a circuit with a BCD up-down counter to which a reset pulse, a clock pulse of 16 x NHz, and a square wave of NHz, which is an up-down signal, are input. .
