Title: A Hybrid Modulation Scheme with Online Peak Common-mode Current Prediction for Three-phase Motor Drive System

Abstract: As various modulation schemes own different merits and drawbacks, applying single method in full modulation range is not an optimal solution. Combine several PWMs with respect to specific operation scenarios is one balanced approach. A hybrid modulation scheme is proposed to realize a multi-factor determined modulation scheme that taking common-mode and differential-mode performance, system loss into consideration. Specifically, for common-mode performance, a smart controller that can actively evaluate the CM performance through artificial intelligence will be introduced. Machine learning methods are employed to actively analyze three popular PWMs (SVPWM, AZSPWM, and DPWMMin) on chip. In this way we can based on the torque and speed command to online determine the best PWM patterns and switching frequency with minimum requirements of computation resources.
