BATTERY SIMULATOR CIRCUIT
When developing a battery charger, using a real battery might be inconvenient. The battery simulator circuit described here is an alternative. The battery input...
BATTERY TRICKLE CHARGER
The circuit is built around an LM317T adjustable voltage regulator. Its output voltage (VOUT) is determined by the formula VOUT= l. 25 (1+R2/R1). I chose a 10-k...
UNIVERSAL BATTERY CHARGER
When power is applied to the circuit, SCR1 is off, so there is no bias-current path to ground; thus, LM317 acts as a current regulator. The LM317 is connected t...
