We study and describe mostly used traditional simplified circuits for full-bridge Zero Voltage Switching-Dual Active Bridge (ZVS-DAB) converter and deduce their mathematical model. On this basis, we propose a high-frequency (HF) mathematical model, which

Analytical calculation of resonant inductance for zero voltage switching in phase-shifted full-bridge converters [PDF]
The phase shift full bridge (PSFB) converter allows high efficiency power conversion at high frequencies through zero voltage switching (ZVS); the parasitic drain-to-source capacitance of the MOSFET is discharged by a resonant inductance before the ...

The arm‐multiplexing modular multilevel converter (AM‐MMC) is a lightweight, high‐power‐density topology whose conventional modulation strategies require large circulating currents to maintain energy balance. This paper establishes a time‐domain analytical model of the AM‐MMC energy‐balance mechanism and proposes an optimised independent arm modulation

A novel ZVS full-bridge converter [PDF]
Conventional soft switching techniques are promising for improvement of efficiency in full bridge converters. However, efficiency of converters with employing such techniques is restricted due to narrow range of zero voltage switching (ZVS). In such situation, several methods have been proposed in the literature to cope with wide range of ZVS from no ...

Based on triple phase‐shift modulation, this paper proposes an integrated optimisation strategy for dual‐active‐bridge converters that simultaneously minimises both root‐mean square (RMS) and peak currents while significantly extending the zero‐voltage‐switching range.

Module Ratio Optimisation Strategy for DC/DC Converters in ISOP Hybrid Solid‐State Transformers
This paper proposes a hybrid solid‐state transformer (SST) topology based on the input‐series output‐parallel (ISOP) architecture, integrating the high controllability of the dual active bridge (DAB) converter with the soft‐switching characteristics of the CLLLC resonant converter, thereby significantly enhancing power conversion efficiency and dynamic

Method to Maximise Utilisation Rate of Flux Linkage in Coreless Transformer
A coreless transformer (CLT) with a maximum utilisation rate of flux linkage is proposed. Compared to existing CLTs, the proposed CLT operates at a significantly lower frequency of 100 kHz, and there is no need for superconductors. Compared with the magnetic‐core transformer (MCT), the proposed CLT has almost the same efficiency, while the gravimetric ...
