Advanced Soft-Switching High Frequency Power Supply with Charge-up Function for IH Cooking Heater

Abstract

This paper is mainly concerned with an advanced soft-switching PWM power supply incorporating boost- half-bridge inverter topology suitable for consumer induction heating. The operating performances of this inverter are illustrated and evaluated on the experimental results, including the power regulation vs. duty cycle characteristics and efficiency characteristics based on the power dissipation as compared with those of previously developed inverter. Its effectiveness is substantially proved on the basis of the experimental results from a practical point of view.
