An Output Control Research of an Induction Heating System Which Uses a 3-Level Inverter

3-레벨 인버터를 이용한 유도가열 시스템의 출력제어 연구

This paper made an induction heating inverter. The inverter is the $20\~40[kHz]$ a resonant inverter which uses a high frequency. We use this inverter and use induction heating. A phasor shift ordered a gate signal to adjust an inverter's output. We verified an output waveform according to the situation of a gate signal through the simulation. We made the inverter really and got the result.
