Design of a DC-DC Converter in Residential Solar Photovoltaic System

Abstract

This study looks at buck type switch mode power supplies (SMPS) suitability in residential solar photovoltaic (PV) applications, of which several factors affecting the desired output response are identified. The main objective of the study is to design robust converter controller, capable of maintaining constant output, with emphasis on good efficiency, stability and low output voltage ripple. One way of achieving this is by using the voltage mode control (VMC) technique. The main tool used for the converter analysis is the LT SPICE software. Converter performance is investigated without and with the developed control technique. Results obtained reveals satisfactory performance of voltage mode control (VMC).
