| Summary: | 碩士 === 國立交通大學 === 電機與控制工程系 === 87 === In this thesis, we propose a design of power circuit for an induction cooker. This is a special application of resonant converter. The main power circuit contains a LC power oscillator, an oscillating timing controller, a temperature curve generator, and a temperature controller. The inductor L is wound around the lower part of the cooking pot so that the eddy current can be uniformly induced around the pot. The uniform eddy current produces uniform temperature distribution. A timing controller of the resonant converter is designed to produce desired amplitude of oscillation current. A power factor corrector is also applied to improve the power factor. The temperature controller has self-adjusting capability. We have also build up a simulink model of the electric cooker and design the self-adjusting controller to control the temperature of the cooker. Our simulation results have shown that the cooker model has the similar heating response as the real one. Our self-adjusting controller can also work very well for the temperature tracking. Most of the hardware has been set up. The controllers are designed by using FLEX10K20RC240.
