nicd charger circuit
hi,
I have a litte different problem.
Suppose, I have a charger to charge optimaly according to my need, and suppose
that I have an apropriate source of power, via AC-DC adapter, to drive my
intended load (led, motor, whtever).
I want to have a system which should run normaly from power source (AC-DC adapter)
and want to have the battery backup for the case when mains power is not there
(through which the AC-DC works).
I know, I can use a UPS for this purpose, but I want to build myself a simple
circuit which can switche from power source to battery backup.
I have tried to search the forum and google, but could not get my answer (perhap
because I dont have specific keywords to search this kind of topic).
If it is discussed already somwhere in this forum, kindly forgive me
and let me know the link.
regards.
