A Novel Buck–Boost Converter Combining KY and Buck Converters

IEEE Transactions on Power Electronics, 2012
In 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.

Two-Switch Semiquadratic Buck Converter

IEEE Transactions on Industrial Electronics, 2017
A two-switch semiquadratic fifth-order buck converter belonging to a minimum-phase family is proposed in this paper. The proposed converter exhibits better dynamic performance, steady-state voltage gain in between conventional buck and quadratic buck converter. In view of this characteristic, it gives more bucking than the traditional buck converter. A

Controlling chaos in buck converters

ICECS'99. Proceedings of ICECS '99. 6th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.99EX357), 2003
A dc-dc buck converter controlled by naturally sampled, constant-frequency pulse width modulation in continuous conduction mode gives rise to a great variety of behaviors, depending on the values of the parameters of the circuit. This paper reexamines the buck converter studied by Fossas and Olivar [1996] and analyzes a method of controlling chaos ...

Digitally controlled buck converter

2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004
Digitally 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-Frequency Buck Converter

IEEE Transactions on Industrial Electronics, 2009
Improving 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

A novel voltage-bucking/boosting converter: KY buck-boost converter

2008 IEEE International Conference on Industrial Technology, 2008
In 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.
