Abstract
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.
