Title:
UNINTERRUPTIBLE POWER SOURCE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/087876
Kind Code:
A1
Abstract:
During powering of a load (3), a control unit (40) supplies AC power from an uninterruptible power source unit (110) to the load (3) by turning a switch (120) off. During regenerative running of the load (3), the control unit (40) supplies regeneration power to an AC power source (1) via the uninterruptible power source unit (110) by turning the switch (120) off when the AC power source (1) can recover the regeneration power. On the other hand, when the AC power source (1) cannot recover the regeneration power, the control unit (40) causes an auxiliary load (130) to consume the regeneration power by turning the switch (120) on.
