Digital Implementation of MPPT Algorithm in Cuk DC/DC Power Converter Based on PIC18F4520 Microcontroller

Abstract

This paper presents a specific application of Cuk's DC/DC converter for a wide range of input and output voltage changes, which was used as a basic converter for the realization of a digital implementation of MPPT algorithm. The control part of the converter is realized on the basis of the microcontroller PIC18F4520, company Microchip. In the paper the basic properties of the realized MPPT converter are given, as well as the key results of experimental tests obtained for different values of input power.
