Duty ratio control ofthree port isolated bidirectional asymmetrical triple active bridge DC-DC converter

Multiport converters are used in interfacing of distributed energy sources with grid/load. Isolated needed applications where converter gain is high and there a requirement isolation. Dual transformer asymmetric triple active bridge offers the advantage reduced circulating current. However, operating range low for variation load source voltage. In this paper duty ratio modulation technique proposed to regulate voltage control power flow both directions. As result new gating scheme, switches operate ZVS, irrespective variations The designed ensure switch utilization. validatedthrough simulation 1kW three port DC-DC converter. It was observerd that regulated wide voltages. single input dual output mode also verified.
