Hi All,
Lets say I have a series-pass darlington pair with a 15V zener on the base. Therefore I will have 14.3V on the emitter wrt ground. Now, if I have a battery that is at 11V and connect it between the emitter and ground the voltage on the emitter will be pulled down by the battery right? I tried this on the bench and this was the case. Will the battery still charge up to 14.3V? I have heard of putting an emitter follower powered by the series pass darlington pair but not entirely sure how that works. Will this emitter follower act as a buffer to prevent the battery from pulling down the charging voltage? If anyone can help clarify this for me that would be great.
Thanks!!
