Researchers at Rensselaer Polytechnic Institute are leading a $2 million study to help widen a bottleneck that is slowing proliferation of large-scale wind and solar power generation. The four-year study aims to develop novel ceramic materials for use in a new approach to energy storage. Rather than batteries, the researchers will develop …
Learn MoreThe results of the theoretical model were verified by comparing it with the measured response of a prototype windmill. The prototype piezoelectric windmill consisting of ten piezoelectric bimorph transducers was operated in the wind speed of 1-12 mph. A power of 7.5 mW at the wind speed of 10 mph was measured across a matching load of 6.7kΩ.

Learn MoreThe power loss of capacitor is due to the ripple current largely. The DC link capacitor ripple current is determined passively by the output current of grid-side converter which is depends on the wind speed. The temperature of capacitor core which is reflection of capacitor lifetime is obtained indirectly according to the heat transfer theory.
