Firstly, the operation principles of a conventional phase-shifted full-bridge (PSFB) zero voltage switching (ZVS) DC-DC converter is briefly introduced. PI control strategy used in voltage loop and current loop is also presented. Secondly, a corresponding simulation model of PSFB based on Saber is built up. The simulation results show a constant output voltage. Phase-shifted and ZVS state have been realized in the simulation results, which verifies the effectiveness of the control system. Finally, the test results of a Prototype based on UCD3138 are also demonstrated in the text.
