The operation mode is "the mains power is isolated from the electrical equipment, and the mains power will not be directly supplied to the electrical equipment". Instead, when UPS arrives, it will be converted into DC power, and then divided into two ways. The other way will be switched back to AC power to supply the electrical equipment. When the mains power supply quality is unstable or power failure occurs, the battery will change from charging to power supply, and it will not be switched back to charging until the mains power returns to normal. "The whole process of UPS power consumption is involved in the whole process". The utility model has the advantages that the output waveform is a sine wave like the commercial power, and is pure without noise. It is not affected by the instability of the commercial power. It can supply power to the "inductive load". As long as the output power of UPS is sufficient, it can supply any commercial power equipment.

UPS UPS keeps its inverter in working state all the time. It converts the external AC into DC through the circuit, and then converts the DC into high-quality sine wave AC through the high-quality inverter and outputs it to the computer. The main function of On-line UPS under power supply condition is to stabilize voltage and prevent radio wave interference; In case of power failure, the standby DC power supply is used to supply power to the inverter. Since the inverter has been working, there is no problem of replacement time. It is suitable for occasions with strict requirements on power supply. One major advantage of online UPS power supply different from backup power supply is that the power supply lasts for a long time, usually several hours, and up to more than ten hours.
