Abstract :
The driving electronics of an haptic tactile interface (HTI) is presented. The stability of its linear power amplifier under the capacitive load of the HTI piezoelectric actuator is analysed and ensured. As the HTI actuator is a resonant one, a topology to compensate its reactive power is presented allowing to reduce the size and the thermal heating of the power stage.
