DC-AC Current Source Converter Using Coupled Inductor

Abstract

This paper proposes a new current source converter using a coupled inductor, which is derived from the circuit of the matrix converter with an additional inductor. The proposed circuit has the bidirectional power conversion ability, providing step-up and step-down operation in each direction, and can switch the direction of the power flow in a few microseconds. This paper describes the principle of operation, the simulation results and the experimental results of the proposed circuit.
