| Abstract: | Based on the analysis of the service performance of the DC 110 V power,the zero-voltage & zero-current-switch-ing(ZVZCS) PWM DC/DC full-bridge converter is selected.The supply circuit and the key component of switch power are designed and calculated.The whole simulation module of control system is built up under the power PSpice platform and the several ways are used in the simulation module.The scheme is verified on the 8 kW prototype converter used in the electric power locomotive engine operating at 20 kHz.The simulative result proves the design is right and feasible. |
