Abstract
본 발명은 인버터의 무효시간 보상장치에 관한 것으로 특히, 기존의 무효시간 보상장치내의 전류극성 검출부(6)와 PWM 발생 및 무효시간 보상부(7) 사이에 전류 극성 검출부(6)에서 출력되는 전류 중 제로 크로싱 부분에서의 케리어 주파수는 낮추어 주고 나머지 부분에서는 정상주파수로 출력시켜 주는 케리어 주파수 변조부(8)를 부가시켜 인버터의 무효시간 보상장치전류의 극성이 바뀌는 부분에서는 인버터의 스위칭 주파수를 낮추어 줌으로써 무효시간이 스위칭의 한 주기에 미치는 영향을 줄일 수 있을 뿐만 아니라, 전류의 극성 검출과는 상관없이 무효시간 보상과 같은 효과를 얻을 수 있어 제품의 신뢰도를 대폭 향상시킬 수 있는 것이다.The present invention relates to an invalid time compensating device of an inverter, in particular, a current output from the current polarity detecting part 6 between the current polarity detecting part 6 and the PWM generation and the invalid time compensating element in the existing invalid time compensating device. By lowering the carrier frequency in the zero crossing part and adding the carrier frequency modulator 8 for outputting the normal frequency in the remaining part, lowering the switching frequency of the inverter in the part where the polarity of the invalid time compensator current of the inverter is changed. In addition to reducing the effect of the dead time on one cycle of switching, it is possible to achieve the same effect as the dead time compensation irrespective of the polarity detection of the current, thereby greatly improving the reliability of the product.
