Design of a micro flywheel energy storage system including power converter

A flywheel energy storage system stores the electrical energy through a fast-spinning flywheel. When necessary, the kinetic energy of the flywheel is converted into the electrical energy by a power converter. In this paper, we present a design procedure of a micro flywheel energy storage system in which an effort is made to optimize not only the components but also the system. A power converter is also designed at the conceptual level. The performance of the power converter is checked through computer simulations.
