Abstract: The efficiency problem on pre-regulation stage of EPC used in spaceborne TWTA is studied in details. Some advice on how to improve the efficiency is given and the simulation results of Zero-Voltage-Switching circuit (ZVS) are presented. The simulation results show that ZVS has a great effect on the improvement of the circuit efficiency.-
