DESIGN AND SIMULATION STUDIES OF BUCK CONVERTER

Power electronics

Power electronic circuits that transform a DC voltage into a different DC voltage level are called DC-DC converters. The DC-DC converters that are the most basic include buck, boost, buck-boost, cuk, and sepic respectively. The function of every DC-DC converter is distinct. In this paper, a buck converter is proposed for developing and verifying the design procedure. Buck converter is a simple step-down DC-DC converter. The duty cycle and voltage source are both important factors in determining the output voltage. All converters are derived based on two basic converters, such as the buck converter and boost converter. The objective of designing converters is to achieve high efficiency and high gain with quick response times. There are so many parameters involved in developing these converters. There is a lot of computer software that has been developed to design these converters. Pspice simulations make it easy to analyze the system's behavior without the need for harmful hardware. The function of the buck converter designed ensures a good efficiency in converting power from 6V to 2.8V and 24v to 9v (2.85A & 1.10A). Pspice simulation results confirmed the effectiveness of the designed buck converter through a simulation study.
