Abstract: This paper describes an efficient bridge DC-DC converter for vehicular applications. Zero voltage switching (ZVS) for active switching is possible with the current-doubler rectifier (CDR). The presented configuration uses the energy stored in the filters' inductors to perform soft switching in a wide load range. Moreover, no voltage oscillations or spikes occur due to the rectifier diodes, and duty cycle loss is low. The simulation and test results detailed the converter's functions. A hardware configuration of 500 watts at 80 kHz has been used to validate the simulation results. A DSP controller board with the model number TMS320F28379D produces real-time gating signals.

Keywords: full bridge DC-DC converter; soft switching; electric vehicles; EVs; zero voltage switching; ZVS; modified pulse width modulation; MPWM; high frequency transformer; HFT.
