Abstract (en)
[origin: WO2018109387A1] The invention concerns a piezoelectric actuator control device comprising a first voltage converter (20) supplying a DC voltage on a DC power supply bus (40) to which is connected a second voltage converter (10) capable of generating a variable excitation voltage under the control of a control computer (50), said second voltage converter comprising two switch half-bridges (11, 12) mounted in parallel with the terminals of a bus capacitor (Cdc), 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 (Umax) 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.
