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

The Harmonic Characteristic of the Advanced Synchronous SVPWM Overmodulation Strategy [PDF]

IEEE Access, 2019
The speed range of the rail transit traction system is very wide and mostly uses the hybrid pulse width modulation. The traditional hybrid pulse width modulation requires different types of modulation strategies to cooperate in switching, which inevitably leads to current and torque ripple and complicates the modulation strategy. In order to solve this

Maximum Power Point Tracking Control via Time‐Varying Vector Equivalent Damping Modulation for Stroke‐Constrained Direct‐Drive Wave Energy Converters

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes a stroke‐constrained MPPT strategy for direct‐drive wave energy converters based on time‐varying modulation of the generator equivalent damping. By combining constrained baseline optimisation, short‐term forward prediction and a smooth damping envelope, the proposed method keeps the device within stroke limits while achieving higher

Coordinated Control and Negative Sequence Suppression Strategy for Grid‐Forming Doubly Fed Induction Generator‐Based Grid Energy Storage System Under Unbalanced Grids

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
For sustainable gravity energy storage, a GFM control framework is established. Streamlined coordinated PI‐R control suppresses negative‐sequence and 100 Hz harmonic ripples. Negative‐sequence currents are eliminated without complex sequence separation. Active power and frequency support are maintained during asymmetrical grid faults.

Recent Advances in Hybrid, Plug‐In, Battery, and Fuel Cell EVs: Control Schemes, Modes, Converter Topologies, and Pros and Cons

IET Electrical Systems in Transportation, Volume 2026, Issue 1, 2026.
Direct current (DC)–DC converters are the backbone of electric vehicle (EV) power trains, enabling efficient and bidirectional energy flow between the battery, high‐voltage (HV) DC link, and auxiliary rails under tight isolation, gain, ripple, and electromagnetic interference (EMI) constraints.

Fractional‐Order Sequence Impedance Modelling and Stability Assessment of Grid‐Connected Virtual Synchronous Generators

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study develops a fractional‐order sequence impedance model for grid‐connected virtual synchronous generators, incorporating realistic broadband characteristics of inductive and capacitive components. Utilising harmonic linearisation and the generalised Nyquist criterion, we demonstrate that optimised fractional‐order models significantly enhance ...

A Hybrid‐Frequency Modulation Method for Cascaded H‐Bridge STATCOM With the Hybrid‐Frequency Power Loop

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
To address DC‐side voltage imbalance in star‐connected cascaded H‐bridge STATCOMs under unbalanced grids, a hybrid‐frequency power loop is introduced to enable interphase power transfer. A hybrid‐frequency PWM (HFPWM) method based on voltage vector superposition is proposed, which maintains superior output characteristics for the intermediate‐frequency
