Multiple-DC-Inputs Direct Electric Power Converter D-EPC Using Multiple Input Leg Reduction Topology and its Control

抄録

A new multiple dc-inputs direct electric-power converter (D-EPC) with legs reduction topology and its control has been developed. D-EPC is a multiple-dc-input inverter and can control power distribution for power sources. The original D-EPC has two positive terminals and a negative terminal in common, and each phase has the same circuit topology with upper arms between the positive terminal and the ac output using bi-directional switches. To reduce the number of bi-directional switch, this paper proposes D-EPC using multiple input leg reduction topology and discusses its control.
