Abstract

본 발명은 전자조리기의 출력 제어장치에 관한 것으로, 종래에는 출력레벨이 아주 낮을 경우 공진주파수가 늘어나게 되어 공진파형이 깨끗하지 못하고 워크코일을 제어하는 파워 트랜지스터가 스위칭할 때 많은 전력 손실을 초래하는 등의 문제점이 있었다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an output control apparatus of an electronic cooker. In the related art, when the output level is very low, the resonance frequency increases, resulting in a large power loss when the power transistor controlling the work coil is not resonant and the resonance waveform is not clean. There was a problem.

따라서 종래의 문제점을 해결하기 위하여 본 발명은 출력레벨을 제어하는 수단으로 듀티제어와 선형출력제어를 조합하여 사용함으로써 광범위한 출력제어를 실현시킬 수 있도록 한다.Therefore, in order to solve the conventional problems, the present invention enables a wide range of output control by using a combination of duty control and linear output control as a means for controlling the output level.
