Abstract: This Project describes how soft-switching technique using zero voltage switching (ZVS) Resonanant converter provides power lossless switching transitions in Dc-to-Dc energy conversion systems. Also it ensures reduced EMI at transitions, avoids high peak currents, better efficiency with high voltage at any frequency. Therefore, it largely reduces the power losses of the converter. Zero voltage switching can best be defined as conventional square wave power conversion during the switch’s on-time with resonant switching transitions. A closed loop series parallel resonant converter with LCL-T configuration has been simulated. The PID controller has been used for closed loop operation ana the performance of proposed converter has been estimated from the open loop to the closed loop resonant converter system. The Mathematical model using MATLAB. The performance of the converter has been found to be better when the PID controller has been considered. The harmonic spectrum and steady state error for various load condition have been obtained to validate the role of controllers. The proposed analysis of simulation results are carried out in MATLAB/SIMULINK model.
