Split-source inverter (SSI) topology is one of the recently proposed single-stage dc-ac power converters, which has some merits compared to other equivalent topologies.

Abstract

Split-source inverter (SSI) topology is one of the recently proposed single-stage dc-ac power converters, which has some merits compared to other equivalent topologies. The SSI was proposed as a two-level topology. Hence, this paper extends its operation from two level operation to a three-level equivalent using the standard three-level flying capacitors voltage-source inverter (VSI) bridge. The extra merit behind this extension is the lower inductance requirements using the same switching frequency, in addition to the conventional merits of the three-level operation. The introduced three-level flying capacitors SSI (FC-SSI) is analyzed and simulated in this paper using MATLAB/Simulink model, where a 1.5kV A system is designed, simulated, and finally implemented experimentally to verify the simulation results.
