종래 주파수 제어에 의한 경우 인접한 워킹 코일 사이에 동작주파수의 차이에 의한 간섭음이 발생하게 되어 워킹 코일의 정확한 출력제어가 이루어지지 않게 되며, 또한 각각의 구성된 인버터만큼 정류수단과 입력단의 정류수단으로부터의 전압을 평활 및 필터링하게 되는 L,C필터를 구성하여야 만 하므로서, 전체 회로가 복잡하게 되며, 기기구성에의 경제성이 결여되는 문제점이 발생하게 된다.According to the conventional frequency control, interference noises are generated between the working coils adjacent to each other by the difference in operating frequency, so that the accurate output control of the working coils is not performed. Since the L and C filters for smoothing and filtering voltages must be configured, the entire circuit becomes complicated, and there is a problem in that the economy of device configuration is lacking.

본 발명은 다출력 제어를 위한 전자유도 가열 조리 장치에 있어서 발생되는 상기와 같은 문제점을 해결하기 위하여 다수개의 인버터 모듈을 병렬로 접속시켜 하나의 인버터회로를 구성하고, 서로 다른 두개의 DC전원공급수단으로부터 전원을 인가하고, 인가된 DC전원에 시분할 제어를 통하여 각각의 인버터 모듈을 제어하여 다출력 제어가 이루어지도록 하므로서, 회로 구성요소를 최소화하며, 다출력 제어시 발생되는 간섭음을 방지하고, 또한 소프트 스위칭 방식을 이용하여 스위칭 손실을 최소화 하므로서, 저소음의 특징을 가질 뿐만 아니라 인버터의 크기 및 경제성을 향상시킬 수 있게 되는 것이다.The present invention constitutes one inverter circuit by connecting a plurality of inverter modules in parallel to solve the above problems generated in the electromagnetic induction heating cooking device for multi-output control, two different DC power supply means By applying power from and controlling each inverter module through time-sharing control to the applied DC power to achieve multi-output control, minimizing circuit components, and preventing interference noise generated during multi-output control, By minimizing the switching loss by using a soft switching method, not only has a low noise characteristics, but also improves the size and economy of the inverter.
