Small-Signal Modeling for Phase-Shift Controlled Resonant Converters

open access: yesIEEE Transactions on Industrial Electronics, 2021
The extended describing function (EDF) method is widely used in modeling the resonant converters. This article finds that the model of the phase-shift controlled resonant converter deduced by this method might be inaccurate especially when the duty-cycle is close to 1. The reason behind it is investigated, showing that derivation of the inverter bridge

Minimum Current Optimization of DBSRC Considering the Dead-Time Effect

open access: yesEnergies, 2022
In a dual-bridge series resonant converter (DBSRC) working at a high switching frequency, the dead-time effect is a serious issue. When the minimum current trajectory (MCT) method is applied, the inductor current cannot be minimized due to the dead-time ...

Triple-Phase-Shift Modulation Strategy for Diode-Clamped Full-Bridge Three-Level Isolated DC/DC Converter

open access: yesIEEE Access, 2020
A triple-phase-shift (TPS) modulation strategy with reduced transformer’s voltage stress is proposed in this paper for the diode-clamped full-bridge (FB) three-level isolated DC/DC converter. The proposed strategy can keep the transformer’s

Optimal Strategy of Triple Phase Shift Transient DC Bias for Dual Active Bridge DC-DC Converter [PDF]

open access: yesE3S Web of Conferences, 2020
Under the traditional phase shift control, dual active bridge DC-DC converter (DAB) has a transient bias on the inductance current when the phase shift ratio changes suddenly, which leads to increase in the current stress of switch tubes and even ...
