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

CONTROL TECHNIQUES FOR DC-DC CONVERTERS WITH IMPROVED PERFORMANCE
ABSTRACT The switched-mode DC-DC converters are some of the most widely used power electronics circuits for its high conversion efficiency and flexible output voltage. These converters used for electronic devices are designed to regulate the output voltage against the changes of the input voltage and load current. This leads to the requirement of more advanced control methods to meet the ... إقراء المزيد

Performance of Induction Heating Power Supply Using Dual Control Mode Pulse-width Modulation–Pulsedensity Modulation High-frequency Inverter
This article presents a novel induction heating power supply. The power supply is based on an auxiliary active edge resonant zero-current soft-switching technique. It consists of single-ended push–pull series load resonant inverter. The proposed inverter is cost effective for high-frequency induction heating consumer appliances. The new multi-resonant high-frequency inverter with series load resonance and edge resonance can regulate its high-frequency ... إقراء المزيد
