Abstract

This paper presents a novel control method for controlling the Modular Matrix Converter (MMxC) in order to achieve balanced capacitor voltages in addition to load voltage and input current control. The proposed control technique has been designed based on independent current control of positive-, negative- and zero-sequence in addition to feed forward power control. The positive-sequence circuit is used to control the input current, the negative-sequence circuit is used to balance the capacitor voltage among MMxC arms and the zero-sequence circuit is used to control the load control. Feed forward power control is used to suppress the capacitor voltage fluctuation. The effectiveness of the proposed control scheme for the MMxC has been verified theoretically using simulation software and experimentally using 4kVA-200V laboratory prototype.
