摘要：
In order to overcome the shortcomings of the traditional multilevel inverter which cannot rise and fall voltage, the Z-source impedance network is introduced into the traditional single-phase full-bridge neutral-point-clamped (NPC) inverter. Through the detailed analysis of the working principle of Z-source single-phase full-bridge NPC inverter, using the single-phase multi-level space vector modulation method, introducing the through-state into the redundant vector, and combing the redundant vector reasonably, the neutral-point potential self-balance and buck-boost output of the inverter can be realized. Based on the theoretical analysis, the simulation and experiment of Z-source single-phase full-bridge NPC inverter are completed. The simulation and experimental results prove the superiority of the topology and the feasibility of the modulation strategy. © 2021, Solar Energy Periodical Office Co., Ltd. All right reserved.
