Using PSPICE a resonant dc-dc converters operating at constant frequency was simulated. The paper concentrates on the working of a half bridge topology employing ZVS techniques. The operation of converter with LC filter in the output is discussed. The design and fabrication was done on a 5V, 50W converter using MOSFET to validate the performance of the converter. The converter has illustrated l...

This paper presents a two-stage DC/DC converter with high efficiency utilized in an electronic power conditioner (EPC), which is widely applicable satellite communications, etc. The galvanically isolated contains two cascaded converters: buck converter, pre-regulator operating under closed-loop condition, and push–pull intended to boost the input voltage, open-loop condition. In switches, inclu...

A novel topology for a soft-switching buck dc– dc converter with a coupled inductor is proposed. The soft-switching buck converter has advantages over the traditional hardswitching converters. The most significant advantage is that it offers a lower switching loss. This converter operates under a zero-current switching condition at turn on and a zero-voltage switching condition at turn off. It ...
