摘要

buck衍生三相整流器是低输出电压和高功率应用的有吸引力的替代品。本文提出了一种单周期控制的三相降压型整流器。传统的正弦脉宽调制(SPWM)通常需要大输出电感来实现低电流畸变。单周期控制，可以控制输入电流在每个开关周期跟随正弦基准;因此，当使用小的输出电感时，即使输出电流纹波较大，也可以实现低电流畸变。所有的发现都得到实验结果的支持。

One-cycle controlled three-phase buck-derived rectifier

Buck-derived three-phase rectifiers are attractive alternatives for low-output voltage and high-power applications. In this paper, three-phase buck-derived rectifiers with one-cycle control are proposed. Conventional sinusoidal pulse width modulation (SPWM) often requires large output inductor in order to achieve low current distortion. With one-cycle control, the input current can be controlled to follow the sinusoidal reference in each switching cycle; therefore, low current distortion can be achieved even if the output current has large ripple when a small output inductor is used. All findings are supported by experimental results.
