Abstract :
Results obtained with an experimental system using microcomputer control of a Cuk converter fed from photovoltaic solar panels are presented. The control system maintains a constant output voltage regardless of the insolation and charge variations. Digital control has the advantages of avoiding reference values, ease of controller parameter adjustment, and the facility to cover a large number of working regimes of the solar panels and the DC/DC power converter. A proportional-integral-derivative (PID) algorithm is used for the converter. The PID parameters are easy to adjust from the user terminal keyboard and the output voltage can be fixed over a wide range of values
