摘要：
A fully software-controlled pulse-width modulated (PWM) rectifier with current link is presented. The PWM rectifier uses six switches to connect the three-phase source to the load directly. Line power factor is controlled while maintaining dc current. The input filter of the PWM rectifier is analyzed and its analysis shows that unity power factor is achieved by lagging of the input current of the PWM rectifier with respect to the source voltage. The PWM technique is developed using a space vector modulation and its implementation is carried out with a minimal control hardware structure based on a 16-b single-chip microcomputer. It is shown via experimental results that the proposed scheme gives good performance for the PWM rectifier with current link.
