| Abstract: | A solar powered battery charger was introduced in this paper,which gave the user the choice of charging either lithium or nickel based batteries.The output of solar panels was converted into a stable voltage to power the charging unit MAX1501 by using the step-down switching regulator LT1777.The control function of the whole system was implemented with the microcontroller PIC16F877A.The design has broad application prospects due to its low cost and high efficiency. |
