摘要
介绍了一种基于单周期控制技术三相PWM整流器,它可以实现单位功率因数和低电流畸变。该整流器不需要乘法器,控制方法简单、可靠。为方便电压环的设计,文中根据特勒根定理推导出了电压环的小信号模型,由此小信号模型设计了电压调节器,最后对实际电路进行了仿真,仿真结果证明了设计的准确性。
This paper introduces a 3-phase PWM rectifier based on one-cycle control. It can achieve unity power factor and low current distortion. The proposed rectifier does not need multipliers, and the control approach is simple and reliable. For the convenience of designing voltage loop, the small-signal model of voltage loop is achieved by applying Tellegen＇s theorem. A voltage controller is designed by applying the small-signal model. Finally the real circuit is simulated. The simulation results prove that the design is reliable.
