说明：  对一种三相无源功率因数校正电路进行了参数的优化和仿真，仿真结果表明，运用Matlab中的SimPowerSystems模块对复杂的电路进行仿真分析和研究，不失为一种准确、直观有效的方法。
(Of a three-phase passive power factor correction circuit parameter optimization and simulation results show that the use of Matlab in SimPowerSystems module circuit simulation of complex analysis and research, after all, a precise, direct and effective way.)
