Hybrid Space Vector PWM Control to Reduce Common-Mode Voltage for Three-Level T-NPC Inverter under Switch-Open-Circuit Fault
This paper proposes a hybrid space vector PWM technique (HSVPWM) that combines conventional SVPWM with virtual SVPWM to reduce common-mode voltage in a three-level T-NPC inverter operating under a switch-open-circuit fault in the neutral-point-connected switch of phase A. First, the concept of virtual space vector is i...
