Abstract
In this paper, an analytical model has been developed to analyze the device power loss and the efficiency of a new four-level π-type converter. The efficiency of the π-type converter has been evaluated against a conventional two-level converter, three-level T-type converter as well as the three-level NPC converter. It has been found out that the four-level π-type converter has a higher efficiency when switching frequency is above 5 kHz. It can achieve 97% efficiency at 50 kHz switching frequency under the rated current. An experimental four-level π-type inverter topology has been built and the efficiency has been validated.
