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...
The paper presents an innovative off-line low profile converter design that delivers 750 W of power at 95%-96% efficiency for nominal input range, using variable frequency topology with high frequency zero voltage switching (ZVS) and zero current switching (ZCS) for primary switchers. Theoretical considerations and practical results are presented for high frequency and high voltage soft-switching...
