Abstract

This article proposes an electrolytic capacitor-less wireless motor drive system. The primary-side electrolytic capacitors are removed through using a three-phase to single-phase matrix converter. The secondary-side electrolytic capacitors are eliminated based on the filter property of the parallel compensation. Moreover, a delta-sigma modulation is used in the proposed system to reduce the grid current harmonics and control the motor speed. Compared to conventional space vector pulse width modulation, delta-sigma modulation can help reduce the device stresses and switching times, allowing the system to operate at a higher switching frequency. To validate the analysis, a prototype operating at 200 kHz is constructed, and a total harmonic distortion of 3.12% is achieved.
