Input current stabilization control of a matrix converter with boost-up functionality

This paper proposes a circuit topology of a matrix converter that adding a boost up function in the input side. The proposed circuit combines the matrix converter with a V-connection AC chopper. A conventional control method can be applied in this matrix converter, so called the virtual indirect method. In order to suppress the input filter resonance, this paper discusses about the input filter design with a damping resistor. In addition, this paper also proposed a stabilization control for the input current that is using a V-connection chopper. The basic operation and validity of the proposed method is confirmed by the simulation and experimental results. The total loss of the proposed circuit is 20 % less than that the loss of the conventional back to back system.
