Abstract: An illustrative example embodiment of a buck-boost converter includes at least three input/output ports, at least three sets of switches, and at least two ripple current limiters. One of the sets of switches is associated with each of the input/output ports. Each of the ripple current limiters is associated with a respective one of the sets of switches between the associated set of switches and another one of the sets of switches.
