摘要：

This study introduces a new single-phase Z-source T-type inverter (SPZT(2)I) with five-level voltage at the output. The proposed inverter allows the power switches in a phase leg conducting simultaneously without any problems. Moreover, the proposed inverter can produce the buck-boost output voltage with a single-stage power conversion. Two shoot-through control strategies are presented to create a five-level voltage at the output. Operating principles, theoretical analysis, and comparison of the proposed SPZT(2)I with the conventional five-level inverters are illustrated. Also, the simulation results using PSIM software are provided. Finally, a 400W prototype is constructed to confirm properties of the proposed concepts.
