摘要：

Considering electromechanical transducers based on dielectric electroactive polymers (DEAP) beside a proper transducer design a feeding power supply is mandatory. In order to increase the energy efficiency these power electronics should provide a bidirectional energy flow. Therefore, in this contribution a bidirectional flyback-converter is investigated. Since the superimposed application-oriented control of the DEAP transducer requires an accurate control of the transducer voltage, in a first step a mathematical description of the flyback-converter for feeding capacitive loads is carried out. Based on this a sensor-based as well as a sensor-less current control is developed that is finally superimposed by a voltage control. The obtained results are experimentally validated by measurements of a realized prototype of the bidirectional flyback-converter feeding a DEAP transducer.
