what if i have a 5-48V Dc supply (consider that it was varying from 5-48V).. and then i want to have an output of steady 12V Dc.. what will i do? do i need a voltage regulator? what value? and do i need a capacitor coupled in input and output? what value? and 2 resistors connected to adjust terminal of VR? what value? plz help me.. ty..

How fast does the voltage vary between 5V and 48V?

A voltage regulator is required, with the information available, you would need a buck/boost switching regulator to keep a 12VDC output (assuming slow change), but without details on current availability and reqirement at 12V, there are too many variables.

actually our input is from 24V DC motor.. driven by a turnstile by about 800rpm.. as we measure the voltage output of the motor.. it ranges by about maximum of 48V.. how will we do to charge it in a 12V DC battery of a motorcycle.. if the required voltage of the battery charger is steady 12V..
