I`m really a beginner when it comes to designing electrical circuits and only have the ability to replicate cicuit designs. I have no idea how to choose and power up a capacitor the way I want it.
So what I need is a capacitor than I can charge up using a low voltage (around 5V) that can then supply with 20V with a device sucking up about 10A but only need to sustain it for 300µs.
Do I start with this equation?
In this equation though, isn`t the delta time the time it takes to charge it up? And is my Vs to be 5V or 0V?
I plan to supply the source the power to the capacitor by using a MOSFET which activates by getting a signal from a micro controller. The micro controller only activates the mosfet for the time needed for the capacitor to charge up? Am I making any sense?
Also, other considerations in helping me design this would be awesome.
