Research on double transistor open circuit fault diagnosis of T‐type three level rectifier based on mixed logical dynamical model

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
In this paper, we proposed an open circuit fault diagnosis method based on mixed logical dynamical model. The experiment verified the effectiveness and feasibility of the fault diagnosis algorithm and reduced fault diagnosis time without increasing algorithm complexity. Abstract The T‐type three‐level rectifier has garnered significant attention due to

Dynamic Performance Enhancement of YASA‐AFFSPM Motors Using Smoothed Active Disturbance Rejection Control and Sensorless Tracking

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
The study introduces an improved active disturbance rejection control (ADRC) method for a 12S/19P YASA‐AFFSSPM motor, utilising a new interpolation‐based function and linear error feedback to simplify tuning and enhance performance. A hybrid sensorless system combining high‐frequency injection and a sliding mode observer provides precise rotor position

Fault‐Tolerant Scheme for Single‐Switch Open‐Circuit Fault in CSI‐Fed Five‐Phase PMSM

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
This paper investigates the single‐switch open‐circuit fault and develops a fault‐tolerant control method that reduces torque ripple and winding copper losses. ABSTRACT Due to their inherent capability to provide short‐circuit fault protection, combined with features, such as high torque density and reduced torque ripple, five‐phase permanent magnet ...

Systematic Implementation and Performance Evaluation of Multiphase Power Converter in Medium Voltage Drive System

IET Energy Systems Integration, Volume 7, Issue 1, January/December 2025.
ABSTRACT Investigation of power converters for use in industrial drive applications finds that these converters are used low reliable components. To overcome this issue, in this paper, advanced power converters (multi‐pulse AC–DC and multilevel DC–AC converter) are developed and implemented to feed vector‐controlled induction motor drive (VCIMD), which

A five‐level nested neutral point‐clamped inverter topology

IET Power Electronics, Volume 18, Issue 1, January/December 2025.
A five‐level nested neutral point‐clamped inverter with reduced blocking‐voltage rating is presented. In each of the inverter‐leg, only one, out the eight power switches, has voltage stress of half of the input voltage. The rest of the switches have voltage stress of one‐quarter of the input voltage.

Simplified double switching SVPWM implementation for three-level VSI

The Journal of Engineering, 2019
A generalised space vector pulse width modulation (SVPWM) framework for the realisation of all double switching states with a memory-optimised method is proposed to reduce the total harmonic distortion (THD) and to provide neutral point voltage balancing

M3D‐DPWM strategy for three‐phase four‐leg inverter with higher harmonic suppression capability

IET Power Electronics
Three‐phase four‐leg inverters are widely used in power systems due to their inherent ability to handle unbalanced loads. However, with conventional 3D space vector pulse width modulation (3D‐SVPWM), high harmonics of large amplitude exist in the output ...
