| Abstract: | It will have more technical and economic advantages to develop induction heating/brazing power supply using new power semiconductor switching device IGBT instead of common thyristor ones. In the paper, the properties of IGBT induction heating/brazing power supply are analyzed. A scheme of high power ultrasonic series resonant power supply is put forward, which adopts the power regulation mode of controllable rectified voltage and frequency tracking technique, and the control circuit based on Phase Lock Loop(PLL) and Gate Array Logic (GAL) Circuit is developed. The working principle is introduced in the article and experiment results are illustrated as well. |
