PARALLEL PROCESSING UNINTERRUPTIBLE POWER SUPPLY(UPS) USING FLYWHEEL ENERGY STORAGE UNIT

The conventional serial UPS using battery energy storage unit is almost universally used. Despite its common usage, the conventional UPS has a number of disadvantages which may be effectively overcome by the application of flywheel energy storage unit This paper proposes a new type of parallel processing UPS using flywheel energy storage unit, which has the features of high power, long life, and high efficiency.
