A three‐phase three‐level converter with shared flying capacitors

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
Three‐phase multilevel converters use a high number of components which increases their size. As specific weight reduction is a work of interest for embedded system applications, this paper presents a topology aiming to optimize volume and mass for a three‐level three‐phase inverter. The number of passive and active components is reduced thanks to the ‘

Harmonic elimination of a fifteen‐level inverter with reduced number of switches using genetic algorithm

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This article presents a Fifteen‐level inverter topology that has a lesser number of switches (12) and can accommodate isolated DC sources. The total harmonic elimination (THD) of the proposed topology using genetic algorithm is within the IEEE 519 standards. Further, the fifteen‐level inverter is implemented in Hardware and firing pulses were generated

Non‐Contact Turn‐Off Time Measurement Method for IGBTs in the Half‐Bridge Submodule Configuration of MMC

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a non‐contact method for measuring the turn‐off time of insulated‐gate bipolar transistor (IGBT) devices in modular multilevel converters (MMC) submodules, using the decay of load‐side common‐mode current. The technique leverages existing current‐sensing infrastructure and avoids intrusive modifications, enabling real‐time ...

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 ...
