A double T‐type H‐bridge reduced switch multilevel inverter for a wide range of DC voltage variations

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a new Double T‐type H‐bridge (DTH) module configuration that can produce 9, 13, 17, 19, 21, and 25 levels using reduced components. Abstract Renewable energy sources are subject to input source uncertainties, which can negatively impact output voltage THD.

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)

Power Quality Enhancement in Grid‐Connected Photovoltaic Systems Using Hybrid Harbor Seal Whiskers Optimization and Interpretable Generalized Additive Neural Networks

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
The integration of solar energy into modern power grids supports sustainability and energy efficiency but also introduces power quality (PQ) challenges such as harmonic distortion, voltage sag, swell, and fluctuations. In order to reduce PQ problems in renewable energy systems (RESs), this research proposes a novel hybrid control strategy that combines
