Abstract

Abstract

This paper studies a new type of LCC-LC resonant converter for the application background of high voltage storage capacitor charging of pulsed plasma thruster (PPT). While keeping the basic characteristics of LCC resonant network, the converter is provided with zero gain point, which makes the converter have the functions of load short-circuit protection and slow start. Compared with LCC resonant converter, the new converter’s working frequency adjustment range is narrower, which is conducive to magnetic integration and power density improvement. The characteristics of high-order LCC-LC resonator are analyzed by fundamental wave analysis and impedance analysis. Based on the analysis, the working range is divided to ensure that the LCC-LC resonant converter can realize soft switch in a wide load range. Aiming at efficient operation of the LCC-LC resonant converter, parameters are optimized. Finally, the functions of the converter are verified by the simulation and the experimental data of the 1 kW prototype.
