A Virtual Space Vector PWM With Active Neutral Point Voltage Control and Common Mode Voltage Suppression for Three-Level NPC Converters

IEEE Transactions on Industrial Electronics, 2021
Virtual space vector pulsewidth modulation (VSVPWM) provides a new approach to neutral point voltage (NPV) control and common mode voltage (CMV) suppression. Few values of coefficients configured in the virtual vectors cannot adjust the NPV continuously.

Overmodulation strategy for four-switch three-phase inverter based on virtual voltage vector

2017 36th Chinese Control Conference (CCC), 2017
The four-switch three-phase inverter (FSTPI) is the fault-tolerant topology of the six-switch three-phase inverter (SSTPI), and the maximum output voltage is limited in the linear modulation region. Therefore, an overmodulation strategy for FSTPI is presented, based on virtual voltage vector and superposition principle, in order to improve the ...

A Virtual Voltage Vector-Based Space Vector Modulation Scheme for Three-Phase Open-Winding Motor Drive with Five-Leg Converter

2022 IEEE Energy Conversion Congress and Exposition (ECCE), 2022
Once the three-phase open-winding motor (TOM) drive system suffers from single open-leg fault, it can be regarded as this TOM is fed by a five-leg converter (FLC) after leg-sharing reconstruction.
