The switch includes a first electrode that receives AC power from an AC power supply and a second electrode connected to a load via an AC bus, and is turned on during a normal operation and turned off during a power failure. The power converter converts DC power from a DC power supply into AC power and outputs it to the AC bus during a power failure. The other power converter converts the AC power received from the AC bus into DC power and stores it in a lithium-ion battery when the load is performing regeneration running, and converts the DC power of the lithium-ion battery into AC power and supplies it to the AC bus when the load is performing power running."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Uninterruptible power supply device","description":"An uninterruptible power supply device includes a switch, a power converter, and another power converter.
