Analysis of DC-DC Sepic Converter with Different MPPT Technique

Abstract

: In this research work the performance of the DC-DC converter has been evaluated with two techniques Constant Voltage control (CVC) and Perturb and Observation (P&O) one by one. The power 456 Software has been used for comparison purpose. The performance of the converter in case of P&O is found satisfactory. The stress on the component is low in case of P&O. The circuit is able to run on the 80 percent duty cycle. The DC-DC efficiency is 90.7 %. The efficiency of input filter is 89.9% has been recorded. Which is higher than the CVC method. The overall performance is found satisfactory. The full irradiance of 1000 W/m2 has been assumed for this testing.
