摘要

讨论了一种改进的脉宽调制(PWM)技术，提高了单相交直流变换器的位移功率因数和输入功率因数。改进后的变换器具有高输入功率因数，并允许直流电压从零到大于源电压的最大值。位移功率因数是统一的，输入功率因数在当前指令的大范围内几乎是统一的。

A single-phase PWM controlled AC to DC converter based on control of unity displacement power factor

A modified pulse-width modulation (PWM) technique that improves the displacement power factor and the input power factor of a single-phase AC to DC converter is discussed. The modified converter is shown to have a high input power factor and allows the of DC voltage from zero to more than the maximum value of the source voltage. The displacement power factor is unity, and the input power factor is almost unity in the wide range of current command.<>
