摘　　要：针对LLC变换器使用PSPICE仿真器进行DC分析和瞬态分析时经常遇到不收敛的问题进行实验,列出了5种有效改进方法。比较了LLC谐振变换器3个参数优化设计的各种方案,提出并验证了运用PSPICE进行多参数优化设计的方法。实验表明,合理运用PSPICE,在谐振开关电源设计中常常会取得比其他方法(软件)更令人满意的效果。Study of high frequency switching power has focused on Inductor-Inductor-Capacitor（LLC） resonant converter recently,and simulation with Personal Simulation Program with Integrated Circuit Emphasis（PSPICE） for switching power has become an important computer-aided analysis and design measure.To solve the non-convergence problems encountered in using the PSPICE simulator for switching power DC analysis and transient analysis,experiments were carried out on how to improve the convergence problem about the LLC PSPICE circuit simulation.Five improved effective methods were listed.Various programs proposed for the design optimization of three parameters of the LLC resonant converter were compared,and the multi-parameter optimization method using PSPICE was presented and validated.Experiments results show that the reasonable use of PSPICE can obtain more satisfactory results than using other methods（software） in the design of switching power supply.
