Title:
SYSTEM AND METHOD FOR INPUTTING MULTIPLE BACKUP POWER SUPPLIES AND OUTPUTTING ONE OR MORE POWER SUPPLIES
Document Type and Number:
WIPO Patent Application WO/2021/258402
Kind Code:
A1
Abstract:
A system and method for inputting multiple backup power supplies and outputting one or more power supplies. The system consists of one or more AC/DC backup power supply input sub-circuits (1), a transformation and convergence sub-circuit (2), one or more DC power supply output sub-circuits (3), one or more AC power supply output sub-circuits (4), etc. In the novel system, multiple (comprising one) backup AC and/or multiple (comprising one) backup DC power supplies are inputted simultaneously, the inputted backup power supplies, regardless of primary and secondary, and are processed and converged to a common circuit, and one or more DC and/or AC power supplies are outputted from the common circuit, so as to ensure that other backup power supplies continue to provide power output when some backup power supplies are accidentally interrupted, thereby ensuring the reliable supply of system power. The invention is particularly suitable for communications, medicine, command, traffic, or other important departments and occasions.
