I was wondering how charge pump circuits and buck/boost modules work. I have a buck/boost module i purchased on ebay, and by hooking up a multimeter to the output, I can verify that from 5V in, i can get get more than 5V out.
Does this mean that i can hook up a solar cell to the input, boost it to 30V, and power a lawnmower? I'm guessing not because even though it is providing a higher voltage, its not boosting current.
So that leads me to wondering if there are similar devices to boost current. Perhaps something like a step-up transformer?
