Abstract :
This paper presents a new ZVT-PWM high frequency inverter. The ZVT operation is achieved in the hole load range by using a simple auxiliary reverse blocking switch in parallel with series resonant capacitor dual duty cycle is used to provide a wide range of output power regulation which is important in many high frequency inverter applications. It is more suitable for induction heating applications The operation and control principle of the proposed high frequency inverter are described and verified through simulated results
