Natural Soft‐Switching Extended Phase‐Shift Control of Dual Active Bridge for High‐Efficiency Battery Charging and Discharging

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This paper adopts a Neutral‐Point‐Clamped H‐bridge (NPC‐H) DAB topology to mitigate voltage stress on the input‐side switches. For both charging and discharging scenarios, a direct current control method is proposed using the output current as the primary control variable.

A Novel Choice Procedure of Magnetic Component Values for Phase Shifted Full Bridge Converters with a Variable Dead-Time Control Method

Energies, 2015
Magnetic components are important parts of the phase shifted full bridge (PSFB) converter. During the dead-time of switches located in the same leg, the converter can achieve zero-voltage-switching (ZVS) by using the energies stored in magnetic ...
