The Double Forward Converter with Synchronous Rectification
Applied Mechanics and Materials, 2015In many switching power supply converters, diode rectifiers are used to obtain the DC output voltage. The conduction loss of these diodes rectifier contributes significantly to the overall power loss, especially for low-voltage, high-current converter applications.

Implementation of an interleaved ZVS forward converter
2009 International Conference on Power Electronics and Drive Systems (PEDS), 2009A parallel zero voltage switching (ZVS) forward converter with half-bridge topology is presented in this paper. Two converter modules are connected in parallel in the output side to share the load current. In the primary side, two converter modules use the same power switches so that the semiconductor devices are reduced in the proposed converter ...

Forwarding Control of a Boost Power Converter
IFAC Proceedings Volumes, 2001Abstract We consider in this paper the asymptotic stabilization of a Boost power converter. The feedback control law is synthesized by using the systematic Forwarding procedure, which allows one to achieve the control design by considering the Boost controlled system as the interconnection of two basic electric circuits. A nonlinear transformation is

An improved multiple output forward converter topology
2010 Joint International Conference on Power Electronics, Drives and Energy Systems & 2010 Power India, 2010An accurately regulated improved multiple output Forward dc-dc converter is proposed. In this topology, each output has its own feedback control circuit for output regulation, that controls the appropriate synchronous rectifiers in the pertinent output stage, to eliminate cross-regulation between outputs.

New On-Off ZCS Double Forward Converter
2010 9th IEEE/IAS International Conference on Industry Applications - INDUSCON 2010, 2010In order to achieve power electronics converters with reduced weight and size the increase of the switching frequencies becomes mandatory. However, switching losses blocks practical implementation of power electronics converters switching at very high frequencies.

A built-in-input filter forward converter
Proceedings of 1994 Power Electronics Specialist Conference - PESC'94, 2002Employing the transformer leakage inductance and two cross-coupled capacitors, a built-in input filter forward converter (BIFFC) configuration is proposed to shape the input current waveform to a nonpulsating fashion. Consequently the ripple and harmonic component of the input current can be significantly reduced without adding a large input filter. In
