Efficiency Analysis of a Synchronous Buck Converter

Abstract

DC-DC converters occupies very significant role in the field of industries or daily life applications. To charge batteries of low voltage associated with continuous power supply (UPS), DC-DC converters are required. Batteries requires low voltage and the accessible voltage at the source is to be advance down to the required level of voltage at the purpose of utility (PoU). While planning DC-DC converters, productivity and effortlessness of the circuit is particularly essential. Basically for the UPS applications, Buck converter can convey the voltage at required level which is exceptionally basic in activity yet the expanded misfortunes in diode can be addresses by utilizing a synchronous Buck converter. By utilizing synchronous Buck converter, the diode conduction misfortunes in Buck converter can be limited, subsequently enhancing the proficiency of the converter. In this paper, Synchronous Buck converter is utilized to charge the batteries of UPS. In this paper Design, displaying of synchronous Buck converter for UPS application was done and its outcomes were gotten by utilizing Matlab/Simulink. An equipment model was additionally created and the equipment comes about were likewise appeared.
