Buck converter with ZVS three level buck clamping
2008 IEEE Power Electronics Specialists Conference, 2008This work presents the study of a three level DC-DC resonant buck converter with buck active clamping (buckbuck), soft switching (ZVS - zero voltage switching) and constant frequency PWM (pulse width modulation). The converter operation in three levels is motivated by the reduction of the maximum switches voltage, maintaining low switching losses.

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.

A new quadratic buck converter
2014 11th International Symposium on Electronics and Telecommunications (ISETC), 2014A new type of quadratic buck converter is presented, analyzed, simulated and experimented in the continuous conduction mode (CCM), the usual way that converters are used. Because of the static conversion ratio dependency on the duty cycle the new converter is ideal for applications where only a small voltage step-down is needed.

A new patented topology — the SEPIC fed buck converter [1, 2] — addresses two critical issues confronting the power electronics field today: efficiency and transient response. A buck converter is integrated into a SEPIC to receive energy from the SEPIC inductors and the outputs of both deliver energy to the load in parallel. When the controlling switch

Bifurcation behavior of the buck converter
IEEE Transactions on Power Electronics, 1996The DC-DC buck power converter, a widely used chopper circuit, exhibits subharmonics and chaos if current feedback is used. This paper investigates the dependence of the system behavior on its parameters. The bifurcation phenomena and a mapping of the parameter space have been presented. This knowledge is vital for designing practical circuits.

On the Chaotic Behaviour of Buck Converters
2007 Canadian Conference on Electrical and Computer Engineering, 2007Power electronic circuits exhibit nonlinear dynamical behaviour due to their inherent inhomogeneity and switching. Among power electronic converters, the DC/DC buck converter is studied with constant-frequency pulse-width modulation feedback control in continuous conduction mode. Phase-space and time-domain plots for several periodic and chaotic orbits

The design of controller of buck converter
2010 International Conference on Computer Application and System Modeling (ICCASM 2010), 2010State-space averaging method is a powerful way to treat analysis and control problems for variable structure systems. The transfer function model of the buck converter is proposed by using the State-space averaging method. A compensator device of the system is designed by using the knowledge of the series compensation.
