circuit for charging mobile battery without using conventional ac supply.

1. 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.

2. 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 .)
