Abstract

본 발명은 암 쇼트 보호장치에 관한 것으로서, 이는 외부의 노이즈나 신호 오동작에 의해 단상 인버터 회로에서 같은 암이 동시에 도통되어 발생되는 인버터회로의 소자 파괴를 배타적 논리합소자를 이용하여 방지하도록 한 것이다.The present invention relates to an arm short protection device, which prevents device destruction of an inverter circuit caused by the same arm conducting simultaneously in a single-phase inverter circuit due to external noise or signal malfunction by using an exclusive logic element.

이와 같은 본 발명은 두 입력 전압을 배타적 논리합하여 출력하는 제1, 제2배타적 논리합수단과; 상기 제1, 제2배타적 논리합수단으로부터 얻어진 서로 다른 전압과 그 전압을 일정시간 지연시켜 얻어진 전압을 논리화하여 출력하는 제1 내지 제4로직수단으로 이루어짐으로서 달성된다.As described above, the present invention includes first and second exclusive OR means for outputting an exclusive OR of two input voltages; This is achieved by consisting of first to fourth logic means for logically outputting different voltages obtained from the first and second exclusive OR means and voltages obtained by delaying the voltage for a predetermined time.
