DC to DC converters are comprehensively applied to several applications in recent subsistence. In this paper hybrid particle swarm optimization tuned model predictive controller (HPSOMPC) is used to attain a better concert of the bidirectional series resonant dc/dc converter while load changes and at starting. The important intention of the proposed controller topology is to improve the steady state stability at output voltage under the variable load conditions. The novel topology has been tested by using simulating tools of MATLAB SIMULINK beneath varying load conditions.
