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.

Energy Management of a Fuel Cell–Supercapacitor Hybrid System With Dedicated Charging Converter

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This paper proposes a coordinated energy management system (EMS) for a fuel cell–supercapacitor hybrid system interfaced through three isolated dual active bridge (DAB) converters. The proposed approach enhances system efficiency by reducing the number of power conversion stages and improving power flow coordination between the fuel cell and ...

PERANCANGAN PEMBANGKIT TEGANGAN TINGGI IMPULS 11,20 kV DENGAN MENERAPKAN ZERO VOLTAGE SWITCHING (ZVS) PADA KONVERTER FLYBACK

Transmisi, 2018
Tegangan tinggi tidak hanya digunakan untuk keperluan transmisi, tetapi juga untuk penelitian di laboratorium. Pada umumnya, tegangan tinggi dibangkitkan menggunakan pembangkit tegangan tinggi konvensional yang berukuran besar. Oleh karena itu, diperlukan rangkaian yang lebih sederhana untuk membangkitkan tegangan tinggi, misalnya menggunakan konverter

Design, Modelling and Control of a MW‐level Hydrogen Converter for an Off‐Grid DC Hydrogen Production System

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a high‐power hydrogen converter specifically designed for megawatt‐level (MW‐scale) off‐grid hydrogen production systems powered by renewable energy sources. A two‐stage ISOP architecture is adopted to fulfill the demanding requirements of high voltage step‐up, high efficiency, low output ripple, and reliable power regulation.

Improved Efficiency of Two‐Stage Partial Power Processing Architectures for Inductive Power Transfer

IET Power Electronics, Volume 19, Issue 1, January/December 2026.
This paper proposes a high‐efficiency two‐stage inductive power transfer (IPT) system with partial power processing to reduce energy losses in conventional cascaded architectures. By processing only partial power through the DC/DC converter, the system minimizes losses, lowers component stress, and improves power density.
