Performance Analysis of DC-DC Buck Converter for Renewable Energy Application

This paper presents the analysis of DC-DC buck converter for renewable energy application. Renewable energy resources mostly produce DC voltages that are used DC-DC converter to convert the DC voltage from one level to another level according to different applications. This DC-DC buck converter is used to step down the high level DC voltage to low level DC voltage. By varying the duty cycle, the performance of buck converter in term of its output voltage can be obtained and analysed. Simulations have been performed using PSIM and validated with hardware implementation. All of the results are recorded and showed that very low voltage can be produced using this topology.
