Abstract

See full text

A method and apparatus for converting power comprising an input bridge having an input adapted for coupling to a DC source, a piezoelectric transformer having an input coupled to an output of the input bridge, and an output bridge having an input coupled to an output of the piezoelectric transformer and an output adapted to couple to a load. A trajectory controller, coupled to the input bridge and output bridge, (1) measures current and voltage in the input bridge, the output bridge or both, (2) measures a current into or out of the piezoelectric transformer, (3) determines switch timing for control signals for the input bridge and output bridge based upon the measured current and/or voltage, and (4) applies the control signals to the input bridge and output bridge.
