2009 International Symposium on Signals, Circuits and Systems, 2009
A special combined forward-flyback converter with a simple two windings transformer, an inductor, an active switch, four diodes and a buffer capacitor is explained. The voltage transfer ratio and the demagnetizing condition are derived. The voltage transfer ratio of the new converter is higher as with the forward converter.

A demagnetization circuit for Forward converters
2009 6th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology, 2009This paper presents a demagnetization circuit able to operate the forward converter with an higher efficiency and with a wider input range. In particular, by the means of few added components, the magnetizing energy and the leakage one are continuously recovered, and the transformer reset and the primary mosfet OFF voltage clamp to the input, both ...

An improved interleaved forward converter
2006 37th IEEE Power Electronics Specialists Conference, 2006Operations and steady-state analysis for an improved interleaved forward converter topology are presented in this paper. Not only Zero-voltage-switching (ZVS) can be achieved through the resonance that exists between the transformers magnetizing inductances and the parasitic capacitance of switches, but also proper transformer reset and lower output ...

Single switch forward converter
2013 IEEE International Conference on Emerging & Sustainable Technologies for Power & ICT in a Developing Society (NIGERCON), 2013This paper presents the design and construction of a regulated, multiple output DC power supply based on the principle of pulse width modulation. DC power supplies based on this principle are called switch mode power supplies and have become the dominant architecture for DC power supplies, due to their capability to handle variable loads, high ...

Buck Integrated Forward Converter
IEEE 36th Conference on Power Electronics Specialists, 2005., 2006An integrated converter is a synthesized converter based on the overall system integration, which is simplified by the system objective and can implement the system functions similar to the discrete converters. An integrated converter consists of converter sets; each converter set has a special function defined by the designer.

Simplified Isolated Forward Converter
INTELEC '82 - International Telecommunications Energy Conference, 1982This thesis pertains to a forward converter consisting only of primary-side control circuits for regulating the output voltage. Control circuits in a conventional forward converter for regulating the output voltage control the on and off times of primary-side switching transistor by comparing the output voltage directly with the reference voltage.

Isolated high voltage‐boosting converter derived from forward converter
International Journal of Circuit Theory and Applications, 2015SummaryA novel isolated high voltage‐boosting converter, derived from the traditional forward converter, is presented in this paper. As compared with the traditional forward converter, the demagnetizing winding of the transformer in the proposed converter is used not only to demagnetize but also to improve the voltage conversion ratio.
