Hi All,
let's say I have designed myself a 30V 3A Regulated DC power supply and want to charge a battery bank with it (bank is about 250 Amp/hr). I would likely need to put an emitter follower stage between the regulated supply and the battery bank as the bank is a very low impedance load.
I have simulated the power supply portion but my sim fails when I decrease the load resistance to less than 1 Ohm.
I know emitter followers are used for driving low impedance loads but how low is too low..the impedance of this battery bank will be in the low milliOms
Any tips would be great and thanks so much,
Joster
