EFFICIENT GATE DRIVERS FOR SWITCHED CAPACITOR CONVERTERS

摘要

A switched capacitor power converter includes active semiconductor switch elements that electrically interconnect capacitors to one another in successive states. Switch driving circuits, each with a control input, power connections, and a drive output are coupled to and for control of one or more of the switch elements. Some of them are configured to be from one or more of the capacitors such that the voltage across power connections of the driving circuit is substantially less than a high voltage terminal of the converter.
