Abstract

Z-source inverters (ZSI) have been widely used in photovoltaic grid-connected applications because of their high efficiency and low cost. However, due to the lack of electrical isolation, such inverters are prone to leakage current (LC), affecting the safety and stability of the system. This paper reviews the current research status of ZSI LC suppression and focuses on the design of new ZSI and its advantages in reducing LC. Through the innovation of the new circuit structure and control strategy, the new inverter effectively eliminates the high-frequency common mode voltage (CMV), thus significantly reducing the LC. In addition, the application of silicon carbide power devices in improving power efficiency is also introduced, and the effectiveness of the proposed scheme is verified by experiments. Future research directions include further optimization of inverter topologies, development of new modulation strategies, and exploration of more efficient LC suppression techniques to improve the reliability and safety of ZSIs.
