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.

A Collaborative Modulation Method of Dual-Side Backflow Power Optimization and Zero-Voltage Switching for Dual Active Bridge

Energies
Dual active bridge (DAB) converters are widely used in DC microgrids because of their superior bidirectional energy flow regulation capability and characteristics, such as wide voltage gain and zero-voltage switching (ZVS).

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.

Accurate analysis of a single-phase dual active bridge converter for ZVS and deadband conditions

, 2017
Simplified equations are used for the analysis of a dual active bridge converter leading to a conservative estimation of the zero voltage switching (ZVS) region. The ZVS is directly affected by the inserted deadband in each leg of the converter.

A Novel Carrier Scheme Combined with DPWM Technique in a ZVS Grid-Connected Three-Phase Inverter

, 2022
In this paper, a novel switching scheme using discontinuous pulse-width modulation (DPWM) for a zero-voltage switching (ZVS) grid-connected three-phase inverter is proposed. ZVS in the main and auxiliary switches was achieved.

Full ZVS-range half bridge converter with variable transient current build-up (VTCB) technique

, 2006
A full ZVS-range variable transient current build-up (VTCB) half-bridge converter is proposed. Since the proposed converter controls the secondary synchronous switch to build-up the current for the ZVS operation in a very short period of time, the ZVS ...
