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 ...

AC to DC Converter Using Microcontroller [PDF]
, 2009 The aim of the project is to obtain a controlled DC output from a standard single phase 230V, 50Hz power supply. For this we first rectified the ac voltage using four diodes. Then the rectified DC voltage is used to get controlled DC voltage output using

Power Converter's IGBT Multi‐State Reliability Analysis for Low Failure Rate Operation
IET Power Electronics, Volume 19, Issue 1, January/December 2026.This paper proposes a multi‐state reliability analysis for IGBTs in power converters, moving beyond the conventional two‐stage model with a constant failure rate and introduces a multi‐state Markov chain model for voltage source converters under different modulation scenarios.
