Triangle Carrier-Based DPWM for Three-Level NPC Inverters [PDF]
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2018 This paper proposes a triangle carrier-based discontinuous pulsewidth modulation (TCB-DPWM) implement method for three-level neutral-point-clamped (3L-NPC) inverters. The function equivalent relationship of the proposed TCB-DPWM and space vector-based DPWM (SVB-DPWM) is mathematically analyzed in this paper.
