Modeling and control of neutral-point-clamping (NPC) three-level inverters fed dual-three phase PMSM drives

2015 IEEE Energy Conversion Congress and Exposition (ECCE), 2015
This paper studies the modeling, switching strategy and control scheme for NPC three-level (NPC-3L) inverter fed dual-three-phase permanent magnet synchronous motor (PMSM) drives. Firstly, the dynamic modeling of the system is described and analyzed.

Vector space decomposition based control of neutral-point-clamping (NPC) three-level inverters fed dual three-phase PMSM drives

IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016
This paper is to study the control scheme for neutral-point-clamping three-level (NPC-3L) inverters fed dual three-phase permanent magnet synchronous motor (PMSM) drives based on vector space decomposition (VSD). The key is to propose a novel VSD based space vector modulation (SVM) strategy for the dual-three phase drives.

A New Three-Level Active Neutral-Point-Clamped (A-NPC) Multilevel Converter Topology

IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019
This paper proposes a new three-level active neutral-point-clamped (A-NPC) converter topology. The classic three-level A-NPC converter's phase-leg (per-phase) comprises the four line-frequency (LF) and two full-cycle-switched high-frequency (HF) pulse-width-modulation (PWM) power switches such as the insulated-gate bipolar transistors (IGBTs).

Zero-voltage switching for the neutral-point-clamped (NPC) inverter

IEEE Transactions on Industrial Electronics, 2002
This paper proposes a transformer-assisted pulsewidth-modulation zero-voltage-switching neutral-point-clamped (NPC) inverter. With the assistance of a transformer-assisted small-rating lossless auxiliary circuit, the main switches work with zero-voltage switching without suffering from any voltage/current spikes, under simple explicit control.

ARCPI resonant snubber for the neutral-point-clamped (NPC) inverter

Conference Record of the 1999 IEEE Industry Applications Conference. Thirty-Forth IAS Annual Meeting (Cat. No.99CH36370), 2003
This paper reports a resonant snubber for the neutral-point-clamped (NPC) inverter using the auxiliary resonant commutated pole inverter (ARCPI) technique. The proposal guarantees zero-voltage switching of the main switches and zero-current switching of the auxiliary switches without incurring any voltage or current spikes across or through the main ...
