Abstract

This paper presents independent control of input current and output voltage for Modular Matrix Converter (MMxC). The MMxC is a multi-level converter without a transformer that converts from the high voltage AC to high voltage AC with arbitrary amplitude and frequency. The control method is difficult due to the simultaneous control of the input current and output voltage. The authors propose a novel control method that is divided into two parts of the positive-sequence circuit for the input current control, and the zero-sequence circuit for the output voltage control. The effectiveness of the proposed control method has been verified by simulations and experiments.
