Abstract

A buck converter efficiently step-downs the voltage level. Financial power transformation expands the robustness of battery, loss of heat energy is lowered and aides in building smaller devices. This can be used in household and industrial areas. The activity of numerous converters relies upon the switching properties of the power elements. Many buck converters utilize the second MOSFET instead of a diode. When the diode turns ON in buck converter, losses occur in the diode, which are called conduction losses, which keep increasing when the ON time of diode increases. Hence, the efficiency of the converter decreases due to these conduction losses. Hence, the synchronous buck converter is proposed, which increases the efficiency reducing the conduction losses. Further improvement in the efficiency can be achieved using an interleaved synchronous buck converter. The main objective of this paper is designing the different buck converters for LED applications.
