Abstract
An intrinsic piezoelectric transformer circuit a piezoelectric transformer circuit is provided that has a primary side component including first and second electrodes, a secondary side component including first and second electrodes, and at least one tertiary component including first and second electrodes. A power bridge is provided which includes one or more switches, each switch has a gate terminal that is directly connected to the second electrode of the tertiary component of the piezoelectric transformer. The first electrode of the tertiary component of the piezoelectric transformer is connected to a reference for the one or more switches of the power bridge. The first electrode of the primary component of the piezoelectric transformer is electrically connected to a power bridge output and the second electrode of the primary component of the piezoelectric transformer is connected to a ground terminal.
