Abstract :
This paper presents a novel prototype of active voltage-clamping capacitor-assisted soft switching PWM inverter operating at a constant frequency variable power (VPCF) regulation scheme, which is suitable for consumer high-power induction-heating cooking appliances. New generation IGBT with a trench gate is particularly improved in order to reduce conduction loss due to its lower saturation voltage characteristics. The soft switching load resonant and quasiresonant inverter using the latest IGBTs designed specially, is evaluated from an experimental point of view
