Buck-boost integrated forward converter

2005 European Conference on Power Electronics and Applications, 2005
An 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.

Sliding mode controlled forward converter

2015 IEEE 9th International Conference on Intelligent Systems and Control (ISCO), 2015
The control methods for DC-DC converters should consider wide input voltage ranges and load variations to guarantee stability under wide operating conditions. The switching action of DC-DC converters makes them variable structure systems. Sliding Mode controller is a robust nonlinear controller that can be used for such variable structure systems.

Alternated forward multi resonant converter

2000 26th Annual Conference of the IEEE Industrial Electronics Society. IECON 2000. 2000 IEEE International Conference on Industrial Electronics, Control and Instrumentation. 21st Century Technologies and Industrial Opportunities (Cat. No.00CH37141), 2002
The high efficiency multi-resonant converter (MRC) is capable of operating at a high frequency because the losses are decreased due to the resonant tank circuit. Such a few MHz high frequency applications provide high power density (W/inch/sup 3/) for the converters. However, the resonant voltage stress across the switch of the resonant tank circuit is

Comparison between full-bridge-forward converter and DAB converter

2013 Brazilian Power Electronics Conference, 2013
This paper analyzes and compares the dual active bridge (DAB) converter and the full-bridge-forward integrated DC-DC converter when applied to a microgrid energy storage bidirectional system that demands high power flow at the discharging operation mode and low power flow at the charging operation mode.

Isolated high voltage‐boosting converter derived from forward converter

International Journal of Circuit Theory and Applications, 2015
SummaryA 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.

Comparison of a new combined four-diode forward-flyback converter with the classical forward converter

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 new ZC-ZVS forward converter

Proceedings of Applied Power Electronics Conference. APEC '96, 2002
This paper presents a steady-state analysis with complete characterization of ZCS-ZVS forward power converter operation. The nondissipative snubber associated with a forward power converter provides the soft commutation switching. The proposed approach allows building a converter with high frequency operation.

A unity power factor forward converter

Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting, 2003
A novel means of obtaining sinusoidal, unity power factor input currents in switched mode power supplies using minimum additional components is presented. The converter is topologically equivalent to a boost converter cascaded by a forward power converter, but is realized using only a single power stage.
