A piezoelectric driving and switching apparatus includes a power supply
circuit having a supply open configuration and positive and negative
closed configurations for transferring energy to an inductor. A
piezoelectric circuit of the apparatus has a piezoelectric open
configuration and a piezoelectric closed configuration whereat the energy
is transferred between the inductor and a first piezoelectric load. The
apparatus includes a capacitive circuit having a capacitive open
configuration and a capacitive closed circuit configuration whereat the
energy is transferred between the inductor and a capacitive load. A
controller circuit of the apparatus includes a switch control for
electrically switching each of the power supply circuit, the
piezoelectric circuit, and the capacitive circuit to selectively and
independently transfer the energy from the power supply to the first
piezoelectric and capacitive loads, and a portion of the energy between
the first piezoelectric and capacitive loads.
