Title:
UNINTERRUPTIBLE POWER SOURCE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/179186
Kind Code:
A1
Abstract:
This uninterruptible power source device comprises: a switch (1a) that allows a first electrode to receive alternating current power from an alternating current power source (51), that connects a second electrode to a load (52) via an alternating current bus (2a), that is on when operations are normal, and that is off during interruptions; a power converter (5) that, during interruptions, converts direct current power form a direct current power source (53) to alternating current power and outputs the alternating current power to the alternating current bus; and a power converter (6) that converts alternating current power received from the alternating current bus to direct current power and stores the direct current power in a lithium ion battery (54) when the load is performing a regenerative operation and that converts the direct current power of the lithium ion battery to alternating current power and supplies the alternating current power to the alternating current bus when the load is performing a power running operation.
