This paper mentions an inverter control scheme suitable for series resonant load. The proposed method changes pulse density modulation (PDM) scheme, and improves power controllability of series resonant load inverter. Unlike pulse width modulation (PWM) method, the proposed scheme does not cause switching noise peaks.
In this paper, a novel type auxiliary active edge resonant snubber assisted zero current soft switching pulse modulation series load resonant inverter using IGBT power modules is proposed for cost effective consumer high-frequency induction heating (IH) appliances. Its operating principle in steady state is described by using each switching mode equivalent operating circuits. The new multi resonant...
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...
