Nowadays, active-front-end rectifiers are increasingly used as grid connected devices. Their efficiency and performances have become relevant for reducing the overall grid losses. This paper thus introduces a predictive hybrid pulse-width-modulation (PH-PWM) technique, adaptable to any space-vector PWM (SVPWM) controller. As opposed to hybrid PWM techniques based on sector partitioning, the PH-PWM...
Hybrid Pulse Width Modulation (PWM) techniques select the appropriate PWM sequence that induces either less current distortion or less switching losses or both. The sequence selection is usually based on an off-line sector partitioning. This simple solution freezes unfortunately the design and prevents any on-line evolution. In this article the improved hybrid PWM technique based on Finite Control...
