Abstract :
A novel LLC resonant converter with semi bridgeless active rectifier (S-BAR) is proposed in this paper. The presented secondary side rectifier topology is applicable for EV battery chargers with wide output voltage range. This topology is achieved by replacing rectifier lower diodes with synchronous switches and regulation by a phase-shifted PWM signal. Simulation results show that the performance of the proposed S-BAR is appropriate for LLC resonant converter and EV battery charger applications. To confirm the performance of the proposed converter experimental results are provided for which output voltage range of 0 to 80 V with an input of 120 V and the full power 600 W.
