本文在分析比较几种换流策略的基础上,着重分析四步换流策略的优点及其安全性,并利用基于空间矢量法的四步换流策略的矩阵整流器的仿真模型,通过Matlab/Simulink7.0软件进行仿真.仿真结果表明基于四步换流策略的矩阵整流器输出的电压所含谐波成分较少,畸变较小,特别在处理电流过零点的脉冲信号,四步换流策略更能做到安全换流.基于该理论分析和仿真结果,采用可编程逻辑器件(CPLD)实现,硬件电路实现结果验证了理论分析和仿真结果的正确性.

The paper analyzed and compared several commutation strategies, especially the four-step commucation strategy. Then, it had been simulated by the matrix rectifier model based on space vector method in the software of Matlab/Simulink7.0. The results show that by using four-steps commutation strategy, the output voltage of Matrix rectifier owned lower harmonic components and small distortion. It is succeed in safety current converter particularly in the procession of zero current. Because of those theorists, the hardware circuit which adopted programmable logic device also proved the theoretical analysis and the simulation results are right.
