Abstract
A 3-Phase 3-Level DC-DC Converter is used for high electric applications. In this paper, all power semiconductor switches are operated under Soft-Switching conditions. The outer-switches are operated within ZVS conditions by using charge transfer through flying capacitors, while the innerswitches are operated within ZVZCS conditions by using leakage inductances and blocking capacitors. Also, this paper describes the operation modes under ZVS and ZCS conditions. In addition, the simulation and experimental results are compared. The practical test is at 5.5 kW rated power and efficiency of 93.40%.
