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.

Selective harmonic elimination pulse width modulation based hybrid multilevel inverter topology with reduced components

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
Abstract In this paper, a reduced switch count single‐phase hybrid multilevel inverter (MLI) is presented. Level generation unit (LGU) and polarity changing unit (PCU) are the two parts of the presented topology which are connected in series. Other advantages of the proposed topology include the reduced switch count, higher level generation with ...

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

A Low-Switching-Frequency Harmonic-Optimized Control Strategy for Modular Multilevel Converters Based on Online SHEPWM Switching-Time Correction

Energies
Low-switching-frequency operation is essential for high-power modular multilevel converters (MMCs), but it makes the simultaneous achievement of low harmonics, fast transient response, and reliable internal control more difficult.
