System for driving a piezoelectric load and method of making same
Abstract:
A driver system comprises a direct current (DC) voltage source and a first bi-directional DC-to-DC converter 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 having a primary side coupled to the DC voltage source and a secondary side coupled to the secondary side of the first bi-directional DC-to-DC converter 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 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.
