I'm looking for a circuit diagram for 12V DC voltage stabilizer for my car.
I found that every time when I start my car, the starter motor will draw so much current that cause the voltage over the ignition coil to drop tremendously.
Most circuits I found need higher input voltage to produce a lower stable voltage, but the only voltage source in a car is from the battery. So it's a
12V-12V DC voltage stabilizer that I'm looking for. Any recommendation?
Thanks, Newbie
