This work deals with the design and simulation of buck converter inverter fed PMBLDC drive system. Permanent Magnet Brushless DC Motor (PMBLDC) is one of the best electrical drives that has increasing popularity due to their high efficiency, reliability, good dynamic response and very low maintenance. This develops the interest of preparing an ideal PMBLDC motor and its associated Drive System ...

Keywords: DC-DC buck converter, Fast transient response, Fuzzy logic controller (FLC). A new low output voltage and fast transient response dc-dc converter is designed in order to feed devices such as microprocessors and DSPs. It is a fast response DC-DC buck converter (FRBC) comprising of two buck converters connected in shunt and controlled by Fuzzy logic controller. First the Linear Control ...

where φn(x,y) are the two-variable polynomials which will be shown to be a suitable generalization of the Hermite-Kampé de Fériet (HKdF) family [1] or a particular case of the Boas-Buck polynomials [2]. As it is well known, the HKdF polynomials are generated by (1.1) when f(x) reduces to an exponential function, while in the case of Boas-Buck polynomials, the argument of f should be replaced by...

This work presents the analysis of radiated EMI problems associated with DC-DC buck converters and the solutions for minimize the reverse recovery of the Drain-Bulk diode of the synchronous switching MOSFET. The DC-DC buck converter topology is used in computers and telecom applications because of its high power efficiency and multiple DC levels. For reducing the reverse recovery and its relate...

The buck converter is one of DC/DC converters that are often used as power supplies. This paper presents parameter tuning methods to obtain circuit element values for the buck converter to minimize the output voltage variation under load changing environments. The conventional method using the concept of the phase margin is extended to have optimal phase margin that gives slightly improved perf...

on the proportion of colour-marked offspring. Labelling of living spermatozoa with fluorescein isothiocyanate was used to establish the identity of spermatozoa recovered from the female tract and/or associated with eggs following mixed inseminations. Little difference in the proportion of the two sperm populations present in the female tract was apparent 6 hr after insemination but, by 13 hr, t...

The DC-DC Converter topologies have received increasing attention in recent years for Low power and high performance applications. The advantages DC-DC buck converters includes increased efficiency, reduced size, reduced EMI, faster transient response and improved reliability. The front end LCL-T in a buck converter is connected in sequence manner to improve the electrical performances and to r...
