Direct control strategy for a four-level three-phase flying-capacitor inverter [PDF]

, 2010
A direct predictive control strategy is proposed for a three-phase four-level flying-capacitor (FC) inverter in this paper. The balancing of the FC voltages, a challenge in applications with small capacitors and low switching frequencies, is done without

Simplified double switching SVPWM implementation for three-level VSI

The Journal of Engineering, 2019
A generalised space vector pulse width modulation (SVPWM) framework for the realisation of all double switching states with a memory-optimised method is proposed to reduce the total harmonic distortion (THD) and to provide neutral point voltage balancing

Voltage-Balancing Strategy for Three-Level Neutral-Point-Clamped Cascade Converter under Sequence Smooth Modulation

Energies, 2020
Three-level neutral-point clamped cascaded converters (3LNPC-CC) are widely used in high power nigh-voltage applications. This paper mainly discusses the open-circuit fault in DC-side of the 3LNPC-CC.

An analogous carrier‐based implementation of virtual space vector modulation with low common‐mode voltage and neutral‐point voltage oscillation elimination for three‐level NPC inverter

IET Power Electronics, 2023
Balancing control of neutral‐point voltage (NPV) and reducing common‐mode voltage (CMV) are crucial for a three‐level neutral‐point‐clamped (NPC) inverter.

Stray voltage symptoms common in dairy cattle eliminated by on-farm neutral isolation [PDF]

, 2000
Plan BDairy farmers with stray voltage symptoms in their cattle often spend thousands of dollars to do neutral isolation, which isolates the primary neutral of the electricity provider from the farm neutral to suppress stray voltage from off-farm sources
