Direct Coupled PV Panel with ĆUK Converter for DC Load Applications

Abstract

The PV systems are becoming gradually more common in distribution and generation systems. The direct coupled CUK converter for DC load applications is connected with PV panel. The ĆUK converter convert DC- DC voltage, in which magnitude of voltage output is not more than or higher than the magnitude of voltage input also the input voltage polarity is reverse to that of output voltage. The ĆUK converter is frequently customized for additional functions like simple transformer separation, high current protection, less ripple current and transfers the power regularly through capacitor. As per the research on the ĆUK converters has rigorous minor switching loss, capable to give unity power factor, decrease in element size, improving efficiency of the system, etc. Operation of ĆUK converter is relatively unusual with that of PWM converters. The effectiveness of proposed methods is to validate ĆUK converter in MATLAB/ SIMULINK.
