gollark: Consdaisdasf.
gollark: I see.
gollark: This is just a bad implementation of a "boost converter", so just look up that.
gollark: The capacitor smooths the very wobbly lines into nonwobbly lines.
gollark: The transistor switches the inductor between being connected to the voltage source's other end and being connected to it only through the diode and capacitor and resistor and such. The inductor "wants" to keep the current through it constant. When it's connected to the other end of the voltage source, it's "charging", and when it is disconnected there is a voltage across it slightly bigger than the voltage source's voltage, which causes a current through the left side of the circuit.
