Design simulation and analysis of a soft switching scheme for DC-DC Boost Converter with a closed loop controller

This paper presents the design of simple but powerful soft switching scheme for a DC-DC Boost Converter with a closed loop control. A new novel soft switching scheme is proposed with a single switch and minimum components which offers load independent operations. Here only one switch is used in this converter which is switched ON at zero current and switched OFF at zero voltage. The proposed Controller is used to improve the dynamic performance of DC-DC converter by achieving a robust output voltage against load disturbances. The duty ratio of the Boost converter is controlled by PI Controller. A 50W/50KHz soft switched PWM Boost converter is simulated and analyzed. The results are simulated using PSIM.
