摘要
摘要:LCLC谐振变换器广泛应用在空间行波管放大器(TWTA)中，起到升压的作用。在LCLC谐振变换器中，具有多个谐振参数，即变压器漏感、串联谐振电容、励磁电感以及并联谐振电容。多个谐振参数增加了LCLC谐振变换器总损耗优化的难度。该文提出一种基于粒子群优化算法的LCLC谐振变换器优化设计方法，解决LCLC谐振变换器由于多个谐振参数造成的总损耗优化困难的问题。首先，推导了LCLC谐振变换器的总损耗公式；其次，采用粒子群优化算法，对LCLC谐振变换器的总损耗进行了优化，得到了总损耗最小时的谐振变换器参数；最后，基于优化的LCLC谐振变换器参数，搭建了LCLC谐振变换器，并进行了一系列实验。实验结果证明了该优化设计方法的有效性。

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.
