Single-Phase Five-Level Quasi-Switched Boost T-Type Inverter

摘要

This paper presents a new combination of a quasi-switched boost network and a single-phase five-level T-type inverter for enhancing the boost factor of the converter. The new modulation scheme for the single-phase five-level quasi-switched boost inverter is carried out to reduce the complexity of inserting shoot-through state without affecting the output voltage amplitude. The comparison of the proposed inverter with the single-phase five-level buck-boost inverters is presented to demonstrate the effectiveness of the proposed inverter. The simulation and experimental results are given to validate the accuracy of the proposed topology.
