Abstract

Z-source inverter is the key part of the new energy equipment. A model of Z-source inverter has been built by using the State Space Average Overall Modeling method. It can achieve the linkage control of the direct zero vector d and modulation factor m. According to the model, a control system adopted MPPT tracking control and voltage & current double loop grid-connected control is designed to realize the coordinated control. SHEPWM modulation strategy is used to ensure that the grid current waveform quality. Z-source photovoltaic grid-connected experimental system has been designed and carried out, and the experimental results verify the validity and correctness of the control system.
