MULTI-MODE UNINTERRUPTIBLE POWER SUPPLY CONTROL METHOD, CONTROL APPARATUS AND CONTROL TERMINAL

The present invention belongs to the technical field of uninterruptible power supplies (UPS), and provides a control method, a control device, a control terminal and a computer-readable storage medium for a multi-mode UPS. The control method includes: obtaining a load rate of the multi-mode UPS; obtaining an operating mode of the multi-mode UPS; determining whether the load rate is less than a preset first threshold; and, if the load rate is less than the first threshold, reducing the operation quantity of power units of the multi-mode UPS corresponding to the operating mode. The present invention improves the operating efficiency of the multi-mode UPS under a light-load condition.
