Closed Loop Control of Soft Switched Single Switch Isolated Step Up DC-DC Converter

T. M. Reshma, G. Renjini

Abstract


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.


Keywords
