| 摘要 |
The present invention relates to a system for controlling an uninterruptible power supply using a lithium-ion battery and, more particularly, to a system for controlling an uninterruptible power supply to supply AC energy, which is supplied from an AC power source, to a load at a constant voltage through the uninterruptible power supply provided between the AC power source and the load. The system for controlling an uninterruptible power supply using a lithium-ion battery comprises: an energy storage device connected to a first node between an AC power source and a load and consisting of a lithium-ion battery to supply a voltage to the load; and a switching unit connected between the first node and the energy storage device and controlling the voltage supplied from the AC power source to the energy storage device and the voltage supplied from the energy storage device to the load. |
