A Novel Low Common-Mode Voltage Modulation Strategy for ANPC-5L Inverter [PDF]

E3S Web of Conferences, 2020
In order to suppress the leakage current of the active neutral point clamed five-level (ANPC-5L) inverter, this paper proposes a novel low common-mode voltage (CMV) modulation strategy based on the space vector modulation thought.

A Varied VSVM Strategy for Balancing the Neutral-Point Voltage of DC-Link Capacitors in Three-Level NPC Converters

Energies, 2015
In the research field of multilevel converters, three-level NPC (neutral-point-clamped) converters, which unfortunately may cause the deviation of the neutral-point voltage of DC-link capacitors, are widely discussed.

Feed-forward Space Vector Modulation for Single-Phase Multilevel Cascade Converters with any DC voltage ratio [PDF]

, 2009
Modulation techniques for multilevel converters can create distorted output voltages and currents if the DC link voltages are unbalanced. This situation can be avoided if the instantaneous DC voltage error is not taken into account in the modulation ...

Asymmetric Inelastic Inert Doublet Dark Matter from Triplet Scalar Leptogenesis [PDF]

, 2011
The nature of dark matter (DM) particles and the mechanism that provides their measured relic abundance are currently unknown. In this paper we investigate inert scalar and vector like fermion doublet DM candidates with a charge asymmetry in the dark ...

Multiphase space vector pulse width modulation

IEEE Transactions on Energy Conversion, 2002
Pole-phase modulation adjusts the pole-phase ratio of an induction machine and requires a multileg, multiphase inverter. This paper analyzes an n-leg, n-phase inverter, and presents techniques for n-phase space vector pulse width modulation (SVPWM). In particular, nine-phase SVPWM is developed and implemented on a nine winding induction machine.

A Modified Neutral-point Voltage Control Strategy for Three-level Inverters Based on Decomposition of Space Vector Diagram

CES Transactions on Electrical Machines and Systems, 2022
Capacitor voltage imbalance is a significant problem for three-level inverters. Due to the mid-point modulation of these inverter topologies, the neutral point potential moves up or down depending on the neutral point current direction creating ...
