Analysis and Control of the Indirect Matrix Converter Fed Permanent Magnet Synchronous Motor Drive System Using One Current Sensor

Background: This paper presents an indirect matrix converter (IMC) fed permanent magnet synchronous motor (PMSM) drive system using only one current sensor in dc link. Method: On the input side (rectifier) of IMC, the space vector modulation (SVM) algorithm based on the dc current is proposed to realize unity power factor. On the output side (inverter) of IMC, the reconstructed algorithm of three-phase output currents is proposed. SVPWM (Space vector pulse width modulation) for the inverter stage of IMC and vector control of PMSM are presented. Conclusion: The prototype of IMC-fed PMSM drive system is implemented and the experimental results validate the performance of the proposed method.
