---------------------------------------------------------------------***--------------------------------------------------------------------Abstract One of the main disadvantages of the buck converter and the interleaved buck converter is the narrow duty cycle which limits the application of the converters for high step-down applications. The interleaved buck converter with high conversion rati...

A new application of the three-phase buck-resonant converter is presented in this paper. It is shown that the analyzed converter is suitable to operate as the rectifier stage in low power wind energy conversion systems (WECS) based on permanent magnet synchronous generators (PMSG) with variable wind speed. As main features, it presents a single controlled switch, simple implementation and contr...

The portable devices development of semiconductor manufacturing technology, conversion efficiency, power consumption, and the size of devices have become the most important design criteria of switching power converters. For portable applications better conveniences extension of battery life and improves the conversion efficiency of power converters .It is essential to develop accurate switching...

Chaotic behaviors of the buck converter were demonstrated by computer simulation studies. The paper implied theoretical considerations and simulations for this kind of converter using a sliding-mode control. The method tried to establish a periodic behavior from a chaotic one in converter behavior. Key-Words: buck converter, sliding-mode, control, bifurcation, periodic, chaotic

This paper presents the design of a 20 MHzhysteresis-controlled CMOS buck converter using pseudo ramp techniques for ultra-low power applications. The proposed buck converter can improve the transient response using hysteresis-controlled and fixed-voltage band techniques. Using pseudo ramp technique, pseudo inductor current signal can be produced to reduce the output voltage ripple. At the same...
