Description

[0001] technical field

[0002] The invention relates to a power supply control system, in particular to a DSP-based uninterruptible power supply control system. Background technique

[0003] With the wide application of the Internet and the increasing popularity of the network, the uninterruptible power supply (UPS), as a guarantee for the safe operation of the computer system, has changed from an independent peripheral device to an integral part of the entire computer network system. The control strategy basically used by the previous UPS is classical control theory or electronic technology (including analog circuits and digital circuits) to realize complex functions. This method is feasible but the integration level is not high. It is difficult to adjust the control parameters after they are determined, and it cannot be well controlled. Intelligent diagnosis of faults and other issues, and the previous UPS can no longer meet the requirements of automation, networking and ...
