bidirectional buck-boost converter
description
unlike the inverting backboost, it uses four switches (also two switches and a diode) to convert a positive input voltage into a positive step-down or boosted output voltage. the voltage conversion ratio m is determined by the on / off duty ratio d of the main switch and is given by the following equation.
m = d / (1-d).
