Abstract

Z-source Inverter (ZSI) is widely used in renewable energy, electric vehicle charging systems, and other fields because of its voltage boost ability and good decoupling characteristics. However, ZSI is prone to problems such as Direct Current (DC) link voltage fluctuation and output current harmonics during operation, which affect stability and dynamic performance. This paper systematically reviews the existing ZSI power decoupling methods, including capacitance decoupling, inductance decoupling, hybrid decoupling, and decoupling based on the control strategy. By analyzing the traditional schemes and their improvement measures (such as parameter optimization and parallel resonant network) in detail, the performance and, advantages and disadvantages of each method are evaluated. In addition, hybrid decoupling strategies and advanced control strategies (such as instantaneous reactive power control (ISR), multi-resonant converter control (MRC), fuzzy control, and neural networks) are introduced, and future research directions and technical challenges are discussed to further improve the performance of ZSI.
