Abstract

A bidirectional switched-capacitor power converter has a first step-up mode and a second step-down mode. The converter includes a capacitor in which in both modes is charged during a first switch topology and then discharged during a second switch topology. Two converters operating out of phase may be disposed in parallel to enable continuous power conversion.
