The work presented in this paper focuses on the power flow control and study of three-limb high frequency transformer enabled three port Dual Active Bridge(DAB) converter, using 1200V and 1700V SiC devices. The advantage of using three-limb transformer is given by the low inter-winding parasitic capacitances due to placement of windings on different limbs and elimination of inter-winding insulations...
A circuit topology of the forward-mode three-level AC/AC converter is proposed. The kind of circuit topologies are constituted of multilevel converter, high frequency transformer, output cycloconverter, and output filters. The converter has the advantages such as concise circuit structure, two-stage power conversions, bidirectional power flow, high frequency electrical isolation, three-level voltage...
