A piezo driver is described that is configured to furnish electric charge to a piezo component and configured to transfer electric charge from the piezo component to a passive energy storage component during various operational states of the piezo driver. In one or more implementations, the piezo driver includes a first passive energy storage component and a second passive energy storage component configured to store electric charge. The piezo driver also includes a voltage converter configured to electrically connect between a piezo component and the first passive energy storage component and the second passive energy storage component. The voltage converter is configured to furnish electric charge from the first passive energy storage component to the piezo component, and vice versa. The voltage converter is also configured to furnish electric charge from the second passive energy storage component to the piezo component, and vice versa.
