| 摘 要： | 电网谐波污染已经引起世界各国的高度重视,功率因数校正（PFC）是治理谐波的一种有效方法。文章对基于单周期控制的三相VIENNA整流器进行了研究,推导了单周期控制三相VIENNA整流器的控制规律,与其它控制方案相比不需要乘法器,不需对电源电压进行检测,控制逻辑比较简单并且以恒定开关频率工作,能够实现单位功率因数校正和低电流畸变。仿真结果验证了理论分析的正确性。

| Abstract: | The attention devoted to reducing grid harmonic pollution is increasing.Power factor correction(PFC) is an effective method to reduce harmonic current in power grid.This paper researches a three-phase VIENNA PWM rectifier based on one-cycle control(OCC).The control rules of a three-phase VIENNA rectifier by one-cycle control are deduced.Compared with other control program does not require multipliers,without the power supply voltage detection,so this control logic is relatively simple and can be achieved with constant switching frequency,the unit power factor correction and low current distortion.The simulation results verify the theoretical analysis. |
