초록
A fully software-controlled pulse-width modulatioed (PWM) rectifier with current link is presented. Line power factor is controlled, while maintaining dc current. The input fitter of the PWM rectifier is analyzed and its analysis, shows that unity power factor is achieved with 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 is implementation is carried out with a minimal control hardware structure based on one 16-bit single-chip microcomputer. It is shown via experimental results that the proposed sheme gives good performance for the PWM rectifier with current link.
