In order to simplify the generation of phase-shifting waveform and reduce the range of phase angle, an angel-fixed method to generate the phase-shifting waveform is presented in this paper. Firstly, it studies the advantages and the topology structure of the bi-directional full-bridge DC-DC converter, compares the advantages and disadvantages of the phase-shifting control and DC voltage variable control, and analyzes the principle of the phase-shifting control. So the soft switching conditions and the transmission characteristics can be concluded. Then, a new method of generating phase-shifting waveform is designed, which is easy to change phase-shifting angle. The method above fixes the waveform of primary side and can only change the waveform phase angel of the secondary side. So it is more convenient to change the phase-shifting angle and beneficial to reduce the transmission power consumption. Moreover, due to the generation of fixed waveform, the phase-shift angle varies in the range of 90 degrees, which is conducive to the realization of soft switching. Finally, the practical experiment proves that it can not only realize the soft switching but also reduce the transmission power consumption.
