摘要
This paper examines the operation of a single-phase solid-state transformer (SST), with a focus on the cascaded H-bridge (CHB) converter in conjunction with multiple dual-active-bridge (DAB) converters. The corresponding control scheme has been proposed for the discussed SST, featuring improved tracking performance and enhanced transient response. Simulation results are finally provided to validate the effectiveness of the proposed control scheme for the single-phase SST.
