N2 - This paper presents an innovative technique for synchronous rectification in the bidirectional CLLC converter with the integrated transformer for plug-in electric vehicle (EV) applications. To improve the efficiency and power density, the integrated transformer is introduced and simulated using Finite Element Analysis (FEA) method. In addition, synchronous rectification method is implemented by controlling the turn-on and turn-off timings based on the phase difference between resonant currents of primary and secondary sides. Furthermore, a simplified closed loop design is discussed and implemented on a digital signal processor (TMS320F28335). The effectiveness of the control loop is verified through the experimental results. A 3.3kW proof-of-concept prototype is built with power density of 1kW/L, a gravimetric power density of 0.9kW/kg and peak efficiency of 97.5%.
