Title:
UNINTERRUPTIBLE POWER SUPPLY
Document Type and Number:
Japanese Patent JP2018007500
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an uninterruptible power supply (UPS) having: an electric generator; a flywheel configured to store a rotational energy and coupled to the electric generator through a gear mechanism; a mechanical motor mechanically coupled to rotate the flywheel; and a control unit.SOLUTION: The control unit is configured to cause the gear mechanism to transfer rotational energy stored in the flywheel to the electric generator and to cause upon detecting utility line failure. The control unit is configured to cause the mechanical motor to rotate the flywheel so as to preserve the flywheel ability to transfer a rotational energy to the electric generator until a backup generator achieves an adequate speed for driving the electric generator.SELECTED DRAWING: Figure 1A
