This Paper presents Simulation and Implementation of Series-Resonant APWM Converter. It is composed of a generalized analysis for the auxiliary network in a modified series-resonant asymmetrical pulse width-modulated (APWM) converter. Telecommunications and computer systems require power supply topologies frequencies. This is a simple topology that operates at a constant in that offer high efficiency and high power density at ever increasing switch is performed to produce a design procedure ant frequency and with near Zero voltage switching losses. It ensures that zero voltage switching (ZVS) is achieved for any series-resonant APWM converter design. New equations that correctly predict the magnitude of auxiliary current are obtained by accounting for the trapezoidal nature of the waveforms associated with high-frequency operation, and the dead time between the switches in the half-bridge. A prototype of the modified topology is constructed and experimental analysis supports the theoretical results. To further improve the performance the use of MOSFET?s as synchronous rectifiers in place of diode rectifiers is proposed. Experimental results verify that ZVS is achieved, and that the proposed design reduces the auxiliary inductor.
