A Novel Buck–Boost Converter Combining KY and Buck Converters
IEEE Transactions on Power Electronics, 2012In this letter, a buck-boost converter, i.e., 2D converter with a positive output voltage, is presented, which combines the KY converter and the traditional synchronously rectified (SR) buck converter. By doing so, the problem in voltage bucking of the KY converter can be solved, thereby increasing the application capability of the KY converter.

A novel voltage-bucking/boosting converter: KY buck-boost converter
2008 IEEE International Conference on Industrial Technology, 2008In this paper, a novel voltage-bucking/boosting converter, named as KY buck-boost converter (i.e. 2D converter) is presented herein. Unlike the traditional buck-boost converter, this converter possesses fast transient responses, similar to the behavior of the buck converter with synchronous rectification.

2016 Biennial International Conference on Power and Energy Systems: Towards Sustainable Energy (PESTSE), 2016
A new drooping gain buck converter is proposed in this paper. In view of the drooping gain characteristic, this converter gives more bucking with the increase in the duty ratio. This feature is exactly reverse to the traditional buck converter. Furthermore, the proposed converter step-down ratio varies in between zero and 0.5.

Magnetically coupled buck converters
2013 IEEE Energy Conversion Congress and Exposition, 2013The use of coupled inductors is now a typical approach to decrease the current ripple in multiphase power converters. Minimizing current ripple increases efficiency, while coupled inductors support a fast transient performance at the same time. This paper proposes a new approach: coupling of inductors between the different power converters with ...

Double-Frequency Buck Converter
IEEE Transactions on Industrial Electronics, 2009Improving the efficiency and dynamics of power converters is a concerned tradeoff in power electronics. The increase of switching frequency can improve the dynamics of power converters, but the efficiency may be degraded. A double-frequency (DF) buck converter is proposed to address this concern. This converter is comprised of two buck cells: one works

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.

Digitally controlled buck converter
2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004Digitally controlled step down converter with different control law algorithms is studied in this paper. The state controller is designed to eliminate the start-up overshoot and reduce maximal dynamic error of load change response, but the state controller is not capable of eliminating the steady-state error under the load change condition. By using an

Double Quadratic Buck Converter
2013 Brazilian Power Electronics Conference, 2013In this paper, a new non-insulated DC-DC converter called Double Quadratic Buck Converter is proposed. This new converter has the advantages of high gain ratio near half range of duty cycle compared to the conventional Buck Converter. The stress voltage over the switches is reduced to half of the value compared to the conventional Quadratic Buck ...
