I'm looking to build another power supply,Ive put together a daisy chain of bits ,parts,assortments..
This will just be a single power supply.
The transformer is your typical step down transformer, that started out as a automotive battery charger that consisted of not much more than two diodes for its guts.
It was rated at 2/10/75 amp..The 75amp was only for intermittent use,the transformer buzz's loud and gets warm just idling in this position..
But 10 amp and it sings along quite well,continuously.
Messing around with the terminals and using a bridge rectifier,I can get 30v DC..I don't expect 10amp @ 30volt
Hence I'm aiming for a power supply that can deliver 15v at 10amp, the rest of the voltage upto 18v is mostly what I'll be using ,but being able Tu pull it down to 1.2volt would be an asset.
Continuously variable current and voltage.
The easy stuff like a few amps of 3.3,5,6,9,12 volt @ 1-3amp are easy to dream up.I have a few lm350's on hand also fixed regulators.
After trolling the net ,cant really find a circuit that fits the bill ,generally the circuits either don't have current limiting,are fixed ,offer only variable voltage or no short circuit protection..
I have various op amps,power transistors,
I kindly ask if anyone has seen or know off a particular circuit ,it would be appreciated if you could slip it by.
