The high switching frequencies in power converters increases the switching losses, and electromagnetic interferences. These losses can be overcome by employing soft switching techniques. The paper introduces a soft switched single switch isolated DC-DC Converter where Switching losses, current and voltage stress can be reduced. The presented converter can be Zero current Switching (ZCS) turn on and Zero-Voltage Switching (ZVS) turn off of diodes and switches, regardless of load variation. The simulation of the circuit with 12V input, 100V/0.1A output is validated using MATLAB.

The presented converter can be Zero current Switching (ZCS) turn on and Zero-Voltage Switching (ZVS) turn off of diodes and switches, regardless of load variation. The simulation of the circuit with 12V input, 100V/0.1A output is validated using MATLAB.
