Beschreibung
Zusammenfassung:	A driver system (100) for a piezo acuator comprises a direct current (DC) voltage source (104) and a first bi-directional DC-to-DC converter (106) having a primary side coupled to the DC voltage source and a secondary side and configured to convert a first voltage on the primary side to a second voltage on the secondary. The driver system also comprises a second bi-directional DC-to-DC converter (108) having a primary side coupled to the DC voltage source (104) and a secondary side coupled to the secondary side of the first bi-directional DC-to-DC converter (106) and configured to convert the first voltage on the primary side to a third voltage on the secondary. The first and second bi-directional DC-to-DC converters (106), (108) are capable of boosting the first voltage, and the second control signal is a complement of the first control signal. A voltage difference between the second and third voltages comprises an output voltage that comprises an amplification of the first control signal.
