Discontinuous PWM Modulation Strategy With Circuit-Level Decoupling Concept of Three-Level Neutral-Point-Clamped (NPC) Inverter

IEEE Transactions on Industrial Electronics, 2013
A new pulse width modulation (PWM) strategy which is an alternative approach of the discontinuous PWM (DPWM) for a three-level neutral-point-clamped (NPC) inverter is developed and presented in this paper. The proposed PWM scheme not only takes advantage of the special properties available in NPC inverters, but also reduces the switching loss of the ...

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 ...

Optimal power control strategies for neutral point clamped (NPC) inverter topology

IEEE Transactions on Industry Applications, 1992
A programmed pulsewidth modulation (PWM) technique for selectively eliminating several lower-order harmonics at the output of a neutral point clamped (NPC) inverter topology is investigated. The switching function approach is utilized to derive relevant analytical expressions for input/output variables.

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).

Model of three level neutral point clamped converter (NPC) for grid connected photovoltaic systems

2015 38th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO), 2015
Photovoltaic modules as direct converters of solar energy into electrical energy are typically connected to the power grid trough standard two level converters. A photovoltaic system can be connected to the power grid if it can satisfy the IEEE standardized conditions set by the power grid operator.
