Abstract

See full text

A piezoelectric actuator control device comprising a first voltage converter supplying a DC voltage on a DC power supply bus to which is connected a second voltage converter capable of generating a variable excitation voltage under the control of a control computer, the second voltage converter comprising two switch half-bridges mounted in parallel with the terminals of a bus capacitor, the control computer being suitable for controlling the two switch half-bridges according to a first control configuration, in which they are controlled independently in order to each supply a voltage in a range between zero and a maximum positive value and according to a second control configuration, in which they are jointly controlled as a full-bridge for supplying a voltage between a minimum negative value and said maximum positive value.
