A review of high voltage drive amplifiers for capacitive actuators

This paper gives an overview of the high voltage amplifiers, which are used to drive capacitive actuators. The amplifiers for both piezoelectric and DEAP (dielectric electro-active polymer) actuator are discussed. The suitable topologies for driving capacitive actuators are illustrated in detail, including linear as well as switched mode amplifiers. In the past much attention has been paid on the driver for piezoelectric actuator. As DEAP is a type of new material, there is not much literature reference for it.
