Application of LCLC Resonant Converters for Space Travelling-wave Tube Amplifiers

The application of LCLC resonant converters for space Travelling-Wave Tube Amplifiers (TWTAs) is investigated in this paper. Based on the working principles under Zero Current Switching (ZCS) and Zero Voltage Switching (ZVS), the equivalent circuit of each mode is derived. In addition, the parameters in each mode are also calculated. In order to validate the effectiveness of the analysis, PSIM simulations are carried out and the results are in accordance with the calculated results. Finally, an LCLC resonant converter with 20 V input, 4600 V output, switching frequency 200 kHz, 280 W output power, 93.38% efficiency is designed. Both the simulation results and the experimental results validate the effectiveness of the analysis.
