Hi.All,
I have built a DC Power Supply. Output Voltage is about 17.5 Volt.
Current capacity is about 30 Amps.
I intend to use this power supply to charge 12 V. Sealed Lead Acid batteries.
On the side of the batteries there is printed two set of values,one for cycle charge and another for standby charge. generally I think the voltage should be around 14 volt for safe charging.
The problem I have is how do I get my 17.5 V to a regulated 14 volt.
I have experimented with a LM 317 K regulator. It's a fantastic IC,but not enough current.Any suggestions as to how I can boost the current output of the LM317K.?
I'm a hobbyist with little technical knowledge,please help. Thank you.
