MOBILE CELL PHONE CHARGER CIRCUIT SIMULATION -K. Sai malleswar THE CIRCUIT BUILT IN PSPICE: (0v dc source is used here to indicate fully discharged battery GRAPH 1 : shows that 170 mA current flows through cell phone battery when fully discharged battery is connected across output terminals.
GRAPH 2: shows the variation of current through cell phone battery when charging occurs. (The current will become zero at required voltage i.e. when battery is fully charged exactly by adjusting VR1 and VR2 .)
