Topic: How do you make a capacitor bank to amp the voltage of a solar panel up to 5v? (Read 740 times) previous topic - next topic

Hi I wish to make a circuit that uses a power source of 1v to be raised up to 5v by a bunch of capacitors.
Any tutorials or tips?

You'll need more than just capacitors...

Go to ebay and search for "5V boost".

I am going to get going.

There's a relationship that exists between current and voltage.
I'd suggest you first check that what you want to do is technically feasible with the equipment.

flying capacitor DC-DC converters are very inefficient for anything but small currents I believe - what current
is the load requiring?

A standard boost converter would prob. be a better answer apart from the bootstrapping issue - with only
1V at the source how to power up (most boost converters need more than that to operate).

You also have to worry about brown-outs when there isn't enough light to power the converter - will
it behave gracefully?

And when you say 1V to me that says 2 PV cells in series (they give about 0.5V under load) - is that the case?
