A practical soft switch bidirectional converter for EV is presented, which can realize the bidirectional flow of energy between the energy storage battery and the motor of the EV. By choosing an appropriate resonant circuit, the soft switch characteristics of the converter in Buck mode and boost mode are analyzed, and a prototype is made. The waveform of the power tube switch state is collected by an oscilloscope, which improves the energy conversion efficiency of the converter and verifies the rationality of the design.
