[Prior Art] In recent years, with the rapid development of the information industry, various kinds of hardware devices such as personal computers, communication devices, and workstations are being widely used in all sectors of society. Since information itself is a product of high added value, people do not want to do everything they can to ensure the security of information and the normal operation of computer systems, so the requirements for power quality are more stringent. Since the power electronic equipment is used in a large amount, the harmonics generated by it cause the power quality to be less than that of natural disasters, etc., so that the public power cannot guarantee the high-quality power supply, and the constant power supply system and the system become the computer or Necessary equipment that is indispensable for shafts and systems.

The charger 15 is connected to the rectifier 13 and the battery 17, and charges the battery 17 when the AC mains power is constantly supplied. Is the inverter 16 coupled to the autotransformer? The second winding and the battery pack, when the AC mains AC is powered off, the inverter 16 converts the voltage of the battery 17 into an AC backup voltage to the second winding of the autotransformer 11.
