Comparison of Fuzzy Logic and PID Control in H‐Bridge Inverter: Performance Analysis and Response Optimization

Engineering Reports, Volume 8, Issue 2, February 2026.
Under identical conditions, we benchmark PID against Fuzzy‐Logic control for a single‐phase H‐bridge inverter. FLC achieves faster rise/settling with lower THD and better disturbance rejection than tuned PID while requiring explicit rule design—offering a reproducible baseline and deployment guidance for power‐quality‐constrained inverter applications.

A Five‐Level Active Neutral‐Point‐Clamped Auxiliary Inverter Based on Reverse Blocking IGBT in Metro Applications

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
We propose a novel five‐level active‐neutral‐point‐clamped converter utilising reverse blocking IGBT (RB‐IGBT). The inverter configuration significantly reduces conduction losses, as only two switches are on the current paths in some switching states. We also propose an optimised state machine‐based modulation strategy.

An Open Circuit Fault Diagnosis Method of T‐Type Three‐Level Inverter

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
In this paper, a fault diagnosis method based on a spatial trajectory diagnosis network model is proposed for T‐type three‐level inverters. By providing a rigorous theoretical derivation of the phase current distortion under switching constraints and neutral‐point voltage shifts, the inherent mapping from time‐domain waveform clipping to 3D trajectory ...

A Compact Air‐Cooled Totally‐Enclosed Integrated Motor Drive for Industrial Applications

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This work presents a totally‐enclosed fan‐cooled integrated motor drive for industrial applications, in which the power converter is housed inside the motor and cooled using the existing fan, with a focus on the thermal behaviour and integration challenges. Using loss models and a combination of finite‐element and lumped‐parameter thermal analysis on a

A type of piecewise and modular energy storage topology achieved by dual carrier cross phase shift SPWM control

IET Power Electronics, 2022
This paper proposes a novel type of piecewise and modular energy storage topology. Compared to the modular multilevel converter (MMC), the proposed topology is not only different in structure but also in concept.
