摘　　要：针对三相二极管整流器整流过程中功率因数低、电流谐波大等问题,结合PFC(Power Factor Correction)技术,设计了一种三相单开关整流器,对其拓扑结构和工作状态进行具体分析,并采用单周期控制方法来控制其输出电压。并以纯电阻负载为例进行MATLAB/simulink仿真实验。结果表明:整流器输入电流谐波含量较低,功率因数接近于1,且输出电压稳定。Regarding of the low power factor and the large harmonic current of three-phase diode rectifier, three-phase single switch rectifier is designed and its topology structure and working condition are analyzed in detail based on PFC （Power Factor Correction）technology, and one-cycle control is adopted to control its output voltage. Finally, simulation experiment is carried out under the circumstance of pure resistance load. The result shows that the harmonic content of the input current of the rectifier is lower, that the power factor approaches to 1 and that the output voltage is stable.
