Abstract
The Z-source inverter topology and operating principle were analyzed, the main work states were derived and the control strategy was studied. According to control requirement of grid-connected PV power generation system, and requirement of electricity quality, a fuzzy PI controller for capacitor voltage of Z-source inverter was presented to overcome bad transient performance of traditional PI controller. The simulation and experimental results verified the rationality and validity of proposed control strategy.
