Datasheet and Circuit Diagram, Posted by: admindata at June 2nd, 2009
What is a designer to do when asked to provide 50 or a 100 per cent more output power beyond what is available from the input? The article below describes us about how this can be accomplished by charging a capacitor bank to store energy until needed (Pump), and discharge it into the load (Dump) in a controlled manner, accordingly.
Providing current to the load from a charged capacitor is a matter of providing the correct amount of charge over a defined period of time according to the article which is well-written by John Betten Application Engineer of Texas Instruments.
We can find sequence such as how to implement the simple concept of providing the correct amount of charge over a defined period of time, an example of a constant power load, when deciding to use a capacitor bank, the benefit of using super capacitors, the example circuit which is shown in figures, how to provide a constant power load, and the article was ended with:
However, even the power demands of a constant power load still can be accommodated by allowing a large voltage droop on a holdup capacitor followed by a switching regulator.
