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 the two lossless auxiliary inductors-assisted voltage source type single ended push pull (SEPP) series resonant high frequency inverter for induction heated fixing roller in copy and printing machines. The simple high-frequency inverter treated here can completely achieve stable zero current soft switching (ZCS) commutation for wide output power regulation ranges and load variations...
This paper presents soft switching zero voltage switching high frequency inverter with reverse blocking single switch for dielectric barrier discharge lamp. The simple high-frequency inverter can completely achieve stable zero voltage soft switching (ZVS) commutation for wide its output power regulation ranges and load variations under its constant high frequency pulse density modulation (PDM) scheme...
In this paper, a novel proposal of the utility-interactive three-phase soft commutation sinewave PWM power conditioner with an auxiliary active resonant DC-link snubber is developed for the fuel cell and the solar power generation systems. The prototype of this power conditioner consists of a PWM boost chopper cascaded three-phase power conditioner, a single two-switch auxiliary resonant DC-link snubber...
This paper presents a new circuit topology of DC bus line switch-assisted full-bridge soft switching PWM inverter type DC-DC converter. The proposed power converter is composed of typical voltage source H full-bridge high frequency PWM inverter with a high frequency transformer link in addition to a single DC bus line side power semiconductor switching device for PWM control scheme and a capacitive...
This paper presents two new circuit topologies of DC busline series active snubber assisted soft switching PWM full-bridge DC-DC power converter acceptable for either utility AC 200 V-rms or AC 400 V-rms input voltage source. Proposed power converters are composed of a typical voltage source full-bridge high frequency PWM inverter using DC busline side series switching devices with the aid of a parallel...
