Abstract

This paper presents a complete steady-state analysis of the novel commutating LC-filter based dual active bridge (DAB). Such converter is aimed to be used in the isolation stage of the power electronics transformer. The topology consists of the LC filter coupled with a DAB. The LC filter allows to boost the input voltage by means of shoot-through state of the inverter switches. The output power of the converter is controlled by means shoot-through and the special phase shift modulation of the DAB. The simulation results of the proposed converter are provided.
