摘要：

Non-linear rectifier loads usually cause heavy distortion in the output voltage of single-phase inverters due to pulsating charging current of the rectifier direct current link capacitor. In this article, a predictive load current-based digital feedforward (PCFF) compensation method is proposed to decrease the inverter voltage distortion associated with the pulsating load current. PCFF control scheme works along with the basic inverter control structure that consists of a repetitive controller and a synchronous reference frame PI controller. The PCFF method further improves the single-phase inverter performance by enhancing its compensation dynamics. The simulation and experimental results show that the proposed control strategy can effectively reduce the total harmonics distortion of the inverter voltage and improve the output voltage quality.
