Abstract :
It is desirable to extract maximum power from solar cells under various sunlight insolation conditions, for battery charging applications. An economical solar battery charger and its control principle are proposed and implemented by the authors. The operating principles, effects of circuit parameters and comparative test results are presented in the paper. The test results show that the proposed charger improves the energy utilization at both low and high insolation conditions
