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.

Investigation of asymmetrical phase-shifted full bridge [power convertors]

Proceedings of IECON '95 - 21st Annual Conference on IEEE Industrial Electronics, 2002
In comparison to forward power converters, bridge topologies make use of parasitic components for resonant transition without the need of additional clamping circuitry. Thus, they are privileged in building high frequency high power converters, even if high efficiency is required.

Comparison of phase-shifted full-bridge converters with auxiliary networks

Proceedings of The 7th International Power Electronics and Motion Control Conference, 2012
The phase-shifted full-bridge zero-voltage-switching (ZVS) converter is widely adopted in industry applications. But it also suffers some problems, such as narrow ZVS range, excessive duty cycle loss, large circulating energy, and severe parasitic ringing. A quantity of methods have been proposed to solve the aforementioned problems.
