Triangle Carrier based Discontinuous PWM for Three-Level NPC Inverters
2018
IEEE Journal of Emerging and Selected Topics in Power Electronics
This paper proposes a triangle carrier based discontinuous PWM (TCB-DPWM) implement method for threelevel neutral-point-clamped (3L-NPC) inverters. The function equivalent relationship of proposed TCB-DPWM and space vector based discontinuous PWM (SVB-DPWM) is mathematically analyzed in this paper. The proposed TCB-DPWM method effectively simplified the implementation of the SVB-DPWM by injecting twice common mode voltages (CMVs) to original modulation signals, where different DPWM methods can
