Abstract :
A maximum power point tracking for separately excited DC motors fed from photovoltaic panels through Cuk and SEPIC converters is given. The Linear Reoriented Coordinate Method is employed to determine the optimal voltage of PV panels. A sensorless positive feedback of motor velocity with a developed control law is realized. Experimental results obtained from both, Cuk and SEPIC converters from an implemented system are given.
