Switching Power Amplifier Series for Piezo Actuators

Super Technologies offers Switching Power Amplifier Series for piezo actuators, from Cedrat Technologies, France. The switching power amplifiers are designed to be compatible with the RK rack family and to perform either linear continuous state or purely on/off states on piezo actuators with extremely fast actuations. The switching technique allows high current required peaks, required by impulse or by high frequency applications on large piezo actuators. The SA75D is the most powerful driver for piezo actuator. It integrates the highest level of power technology to drive piezo actuators up to 30 A. It could be integrated in a 42F4H rack for 1 channel or in an 84F4H rack for up to 3 channels. In the 3 channels configuration, 3 independent converters SC75D will be added to supply the 3 SA75D. The SP75A is a 2 states power driving board. Only two positions can be obtained: off position at rest (-20 V DC); on position (150 Volt DC). The two positions are controlled by a TTL signal. The overshoot of the piezo actuator can be reduced after calibrations of the slew rate. The SP75A-x can be equipped with the push pull option. The switching amplifiers have been developed in collaboration with the G2ELAB of UJF grenoble in the context of AVIBUS and PPSMPAB projects. They can drive large piezo actuators allowing fast power actuation as requested in machine tools or helicopter flap applications.
