Hardware Implementation and Steady-State Analysis of ZVS-PWM Cuk Converter Based MPPT for Solar PV Module

Abstract The main objective of this paper is to design and implement a ZVS-PWM Cuk converter to extract maximum power from solar PV module which uses Adaptive Perturb and Observer (APAO) algorithm. ZVS-PWM cuk converter is the interface between the solar PV panel and load. In order to improve electromagnetic compatibility and to reduce the switching losses across the switches, the soft switching (ZVS) has been implemented for Cuk converter, resulting in high converter conversion efficiency with less EMI at high-frequency operation. The harmonic content that each of the converter circuit produces is examined using FFT analysis. The implemented adaptive PAO algorithm improves the steady state stability and dynamic response when compared to the conventional PAO method. This algorithm is simulated using MATLAB/Simulink and implemented using ATMEGA16 micro controller. Hardware validation is carried out for the converter with the solar PV panel with rating of 37W, and operating at 25 kHz.
