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.

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 ...

, 2015 The decay Zc(3900)±→ωπ± is searched for using data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of-mass energies s√=4.23 and 4.26 GeV. No significant signal for the Zc(3900)± is found, and upper limits at the 90% confidence level on the Born cross section for the process e+e−→Zc(3900)±π∓→ωπ+π− are determined

Symmetry and Duality in ZCS and ZVS Quasi-Resonant Buck, Boost, and Buck–Boost DC–DC Converters
EnergiesQuasi-resonant (QR) DC–DC converters with PWM control achieve soft switching by shaping the commutation transient through a local resonant process. This paper proposes a symmetry-based unified perspective on classical QR converters by interpreting zero ...

Interleaved Active-Clamping Converter With ZVS/ZCS Features
IEEE Transactions on Power Electronics, 2010 In this paper, an interleaved soft-switching dc-to-dc converter configuration is proposed. It consists of two parts: the primary side is a constant-frequency asymmetrical converter with active-clamp feature and the secondary side is a series-resonant tank circuit.
