Abstract
본 발명은 유도가열조리기의 전력 제어방법에 관한 것으로, 종래에는 전력 제어를 비교회로를 이용하여 수행함으로써 한정된 전력 제어와 전력 제어단계가 증가할 경우엔 스위징소자가 증가해야 함에 따라 원가 상승의 문제와 입력 전원의 변동등의 불안정 요인에 대해서 전력 제어가 불균일 해지는 등의 문제점이 있다. 따라서, 본 발명은 마이크로 프로세서 자체의 타이머를 이용하여 PWM 펄스폭을 조정하여 전력 제어를 행하도록 함으로써 별도의 비교회로를 사용하지 않아도 원하는 단계의 전력 제어가 가능함에 따라 원가 상승의 부담을 해소하고, 입력 전원의 변동에 대해서도 즉시 전력 제어의 증감을 제어 할 수 있어 전력 제어의 안정성을 도모할 수 있도록 한다.The present invention relates to a power control method of an induction heating cooker, and in the related art, when the limited power control and the power control step are increased by performing power control using a comparison circuit, the problem of cost increase as the number of switching elements increases. There is a problem such as uneven power control against instability factors such as fluctuations in and input power. Therefore, the present invention is to control the PWM pulse width by using the timer of the microprocessor itself to perform power control to eliminate the burden of cost increase as it is possible to control the power of the desired stage without using a separate comparison circuit, It is possible to control the increase or decrease of the power control immediately even with the fluctuation of the input power, so that the power control can be stabilized.
