Semiconductor Power Converterless Voltage Sag
Abstract- Flywheel energy storage systems are focused asuninterruptible power supplies (UPS) from the viewpoint of
environmental friendliness and high durability performance.
Using a low-speed, heavy, simple flywheel, and a low-cost
squirrel-cage induction motor/generator, this paper proposes
two applications as follows; 1) 11-kW voltage sag com-
pensator using a capacitor self-excited induction generator
without semiconductor converters; 2) UPS composed of
the flywheel system and an engine generator. From some
experimental results, an ideal voltage sag compensator and
UPS are realized by the low-technology flywheel system.
