Abstract

This paper shows an experimental demonstration of a high efficiency step-down circuit for a dielectric elastomer generator. The step-down circuit, consisting of a surge arrester and a transformer, is classified as a passively-switched flyback converter and can transfer energy efficiently. In the experiments, the efficiency of the step-down circuit is nearly 100 times higher than that of a Zener diode, which is used for the simplest step-down conversion. Also, we discovered that the harvested power and the efficiency are improved better if the breakdown voltage of the surge arrester is selected to be higher. Finally, the wireless transmission of a microprocessor is demonstrated using the step-down circuit connected to a dielectric elastomer generator and a self-priming circuit.
