Research on hybrid SHEPWM based on different switching patterns

International Journal of Power Electronics and Drive Systems (IJPEDS), 2019
<span>This paper presents a hybrid pulse width modulation (HPWM) strategy based on different switching patterns of selective harmonic elimination pulse width modulation (SHEPWM) for the three-level neutral point clamped (3L-NPC) converter. Specific low-order harmonics can be eliminated by SHEPWM at low switching frequency, while the remaining ...

Online control of AC/AC converter based SHEPWM technique [PDF]

2014 49th International Universities Power Engineering Conference (UPEC), 2014
Conventional online control of AC/AC converter controlled by the selective harmonic elimination pulse width modulation technique (SHEPWM) is based on storing the offline calculated switching angle values in a form of lookup table. Then the required switching pattern of certain modulation index (M) is searched through the lookup table.

Current Control Of Grid Tied Inverter through SHEPWM Method

Energy Procedia, 2017
Abstract The grid connected inverters are increasingly used nowadays in distributed generation and smart grid. But the main challenge in grid connected systems is their compatibility with grid utility and also to maintain the harmonic contents of output current. To overcome these challenges, different current control techniques are used so far.

A Multi‐Objective Optimal Synchronous Modulation Strategy for Three‐Level Converter Through Switching Angle Regulation

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a novel power loss reduction PWM (PLRPWM) strategy for three‐level neutral point clamped inverters. The proposed strategy aims to achieve multi‐objective optimisation by balancing low output harmonics, reduced switching losses and a balanced neutral‐point potential. ABSTRACT Three‐level neutral point clamped (3L‐NPC) converters have
