Abstract
A flywheel energy storage system includes a flywheel housing that encloses a flywheel rotor, a motor/alternator, and a power electronics unit. The power electronics unit includes a power electronics housing directly mounted on the flywheel housing, and one or more power electronic circuits enclosed by the power electronics housing. The direct mounting of the power electronics housing on the flywheel housing enables thermal distribution for passive cooling purposes. The design of the flywheel energy storage system also reduces the vibrational forces imparted by the power electronics housing on the flywheel housing.
