In radiator thermostat applications, DEAP (Dielectric Electro Active Polymer) actuator tends to be a good candidate to replace the conventional self-actuating or step motor based actuator due to its intrinsic advantages. The capacitive property and high voltage (HV) driving demand of DEAP actuator make a high voltage capacitive load driving system to be necessary. The only energy source battery determines it needs to be an autonomous system. The detailed system specifications have been introduced and the corresponding system level design has been proposed. In addition, the detailed design and implementation information has been provided as well, including the power and control stage inside the high voltage converter, the output voltage measurement circuit, the feedback control, etc. Finally, the experimental results have been provided to validate the capability and performance of the driving system.

“…However, not much research related to the development of driving converters for DEAP actuators has been carried out, especially for the driving devices with small size, high efficiency as well as low cost [4]. The object of this paper is to develop a bidirectional flyback based converter in order to drive DEAP actuator and perform a detailed behavior analysis for the operation of this high voltage converter.…”

Flyback converters are widely used in several applications, however, with this topology it is very challenging to achieve high voltage operation especially with very high step-up ratio (>500) within limited space. This paper presents a new flyback-based topology which utilizes primary parallel and secondary series transformer connection in order to achieve very high step-up ratio (up to 650) as well as high voltage operation (~2 kV) in a small volume. The topology is presented and analyzed. The advantages and disadvantages of the proposed topology are discussed. A prototype used to verify the proposed topology has been implemented. Finally, experimental results are used to validate the performance of the proposed topology.
