An assessment of H‐bridge less grid‐tied multilevel inverter with minimum device count and lesser total standing voltage

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
An innovative switched‐capacitor‐based inverter is proposed in this article. The suggested converter can produce a five‐level output voltage by utilizing minimal components (single dc source, six switches, and one capacitor). The effectiveness of the suggested inverter is verified by experimental results using hardware in loop OPAL‐RT OP4510.

Active Voltage Balancing Control of 9‐Level Multicell‐Based A‐NPC Inverters

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
We present a optimization‐free PWM control for single‐phase 9‐level FC A‐NPC inverters that converts measured current and capacitor voltages into logic equations to both balance FC voltages and generate the commanded levels. By removing objective functions/optimizers, it enables fast, simple implementation, with experiments showing robust performance ...

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

Hybrid Hysteresis–FOC Strategy With Extended Clarke Transformation For High‐Performance Five‐Phase PMSM Drives

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
The hysteresis control strategy used in FOC is available in three‐phase (3‐phase) motor control. However, our research article implements the 5‐phase inverter drive for controlling the 5‐phase PMSM motor with HCC–FOC, which was not addressed earlier, that reduces the current ripple in the inverter drive. ABSTRACT The research on the five phase (5‐phase)
