| Abstract: | Based on analysis of the operating principle of phase-shifting full-bridge zero voltage PWM converter,a 12kW electric power supply was designed and tested. The simulation model of main circuit and control circuit of such a kind of power supply was built and the open-loop log frequency characteristics were obtained successfully. The simulation results shows that the design scheme is feasible and the high accuracy and dynamic characteristic of output voltage and current could meel design requirements completely. |
