Abstract

Abstract

The LCLC resonant converters are universally applied to the space Travelling-Wave Tube Amplifiers (TWTA), to boost the input voltage. In an LCLC resonant converter, several resonant components, including the leakage inductance, the serial resonant capacitor, the magnetizing inductance and the parallel resonant capacitor, are included in the resonant tank, which complicates the optimal design of total power loss in the LCLC resonant converter. In order to solve this problem, in this paper, a Particle-Swarm-Optimization (PSO)algorithm based, optimal design method of the LCLC resonant converter is proposed. At first, the total power loss of the LCLC resonant converter is derived based on the circuit analysis; After that, the total power loss of the LCLC resonant converter is optimized by the Particle-Swarm-Optimization algorithm and the optimal resonant parameters are calculated. Finally, based on the optimal resonant parameters, the optimal LCLC resonant converter is built. The proposed optimal design method is validated by experiments.
