Working principle of ups power supply:
UPS power supply is a backup power supply that works by converting alternating current to direct current and storing the direct current in batteries. When the power grid suddenly fails or the voltage fluctuates, the UPS power supply will detect and start immediately, convert the stored battery energy into alternating current, and continue to supply power to the equipment to avoid the loss of data or equipment. At the same time, after the grid voltage stabilizes, the UPS power supply will automatically switch back to the grid power supply, and at the same time charge the battery for the next power outage. Therefore, UPS power supply is usually used for key equipment that requires stable and reliable power supply, such as servers, computers, communication systems, etc.
