Advantage of GaN in Phase Shift Full Bridges

2019 IEEE 7th Workshop on Wide Bandgap Power Devices and Applications (WiPDA), 2019
GaN FET and Si MOSFET have very different voltage dependence of output capacitance (Coss). Due to the difference, GaN FET offers low C oss stored charge (Q oss ) while Si MOSFET gives low Coss stored energy (E oss ). As low Q oss benefits reduction of resonant energy and time, GaN FET is ideal for resonant type of half or full bridges requiring low ...

Voltage Oscillation Reduction Technique for Phase-Shift Full-Bridge Converter

IEEE Transactions on Industrial Electronics, 2006
A conventional phase-shift full-bridge converter (PSFB) has a serious voltage oscillation problem across the secondary rectifier diodes. To overcome this problem, a new voltage oscillation reduction technique (VORT), which effectively reduces the rectifier voltage oscillation by a simple manner, is proposed.

Modeling of common-mode noise in phase-shift full-bridge converter

IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016
The common-mode (CM) noise modeling for a power converter mainly focuses on the identification of high dv/dt nodes in the circuit and the related parasitic capacitance. For phase-shift full-bridge (PSFB) converter, the inter-winding capacitance of the transformer and the parasitic capacitance between the mid-point nodes from each leg and the ground are

Efficiency optimization for phase‐shifted full‐bridge converter with variable frequency control

International Journal of Circuit Theory and Applications, 2023
AbstractIn this paper, a control method combined with variable frequency and phase shifting is proposed, the primary purpose of which is to optimize the operating efficiency of the phase‐shift full‐bridge (PSFB) DC‐DC converter. By modeling the losses of the PSFB converter, the optimal switching frequency related to the load conditions is found.
