Performance evaluation of single-phase full bridge grid-connected converter with reduced switching losses

This paper introduces an effective technique to reduce semiconductor switching losses in one branch. The switching losses are reduced by using zero crossing technique to control one branch, and the other branch will be controlled by hysteresis current control. The overall switching losses between standard PWM and the proposed will be compared. Performances of the proposed controllers are compared with the performances of the conventional fixed-band. The simulation results verify the correctness of operation of the proposed switching technique by using MATLAB/Simulink.
