New high-frequency linked half-bridge softswitching PWM DC–DC converter with input DC rail side active edge resonant snubbers
This study presents a new circuit topology of the active edge resonant snubber-assisted half-bridge softswitching PWM inverter-type DC–DC high-power converter for DC bus feeding power plants. The proposed DC–DC power converter is composed of a typical voltage source-fed half-bridge high-frequency PWM inverter with a high-frequency planar transformer link in addition to input DC busline side power semi-conductor switching devices for ... إقراء المزيد

Design and Performance Analysis of Series Resonant Inverters for Induction Heating Applications
ABSTRACT This paper presents a cost effective series resonant inverters for high-frequency induction heating consumer appliances. The new multi-resonant high-frequency inverter with series load resonance can regulate its output power under the constant-frequency. The high-frequency pulse-density modulation strategy is demonstrated for a high-frequency soft-switching of the proposed inverter. This type of inverter produces an approximately sinusoidal waveform at a high ... إقراء المزيد
