Optionally, the second mains input end may be homologous to the first mains input end, or may even share an input interface of the power supply system with the first mains input end, and be used as a built-in bypass of the power supply system. The second mains input end can be a built-in voltage transformation unit, so that the input voltage of the second mains input end is reduced to be within the output range of the uninterrupted power supply with alternating current output.
Optionally, in some optional scenarios, if the output voltage of the phase-shifting transformer can meet the load requirement (for example, the load is 220V single-phase input, and the output end of the phase-shifting transformer is 220V single-phase output), then the second mains input end can directly draw power from the output end of the phase-shifting transformer.
Optionally, if the output voltage of the phase-shifting transformer cannot meet the load requirement (for example, the load is 220V single-phase input, and the output end of the phase-shifting transformer is 380V single-phase output or other voltage system which does not meet the load), but the second mains supply meeting the load requirement is available outside the power supply system, the corresponding mains supply can be accessed through the second mains supply input end so as to set a corresponding load power supply bypass.
Optionally, the first conducting end of the gating module is electrically connected to the second mains input end, and the second conducting end of the gating module is electrically connected to the output end of the uninterruptible power supply.

Optionally, when the power supply of the first mains input end is normal, or the charge capacity of the uninterruptible power supply electrically connected to the second mains input end through the gating module is sufficient, the gating module is in an off state (i.e., the second mains input end is disconnected from the uninterruptible power supply through the gating module), and the power supply system uses the electric energy converted by the first mains input end or uses the discharge of the uninterruptible power supply to supply power to the load.
Optionally, when the power supply of the first mains supply input end is abnormal, and the storage capacity of the uninterruptible power supply electrically connected with the second mains supply input end through the gating module reaches the minimum electric capacity threshold, the gating module is in a closed state (namely, the second mains supply input end is connected with the uninterruptible power supply through the gating module), the power supply system can utilize the second mains supply input end to supply power to a load at the moment, and when the second mains supply input end supplies power to the load and has surplus power supply capacity, the power supply allowance of the second mains supply input end can be converted into direct current through the voltage transformation unit of the uninterruptible power supply so as to charge the energy storage unit in the uninterruptible power supply.
Or when the power supply of the first mains supply input end is abnormal and the discharge amount of the uninterruptible power supply electrically connected with the second mains supply input end through the gating module is insufficient to meet the load demand, the gating module is in a closed state (namely, the second mains supply input end is connected with the uninterruptible power supply through the gating module), and the power supply system can supply power to the load by using the uninterruptible power supply and the second mains supply input end at the same time, namely, the uninterruptible power supply is controlled to discharge the load, and the uninterruptible power supply is complemented by the second mains supply input end to supply the part with insufficient power for the load, so that the normal operation of the load is ensured to be maintained.
The second mains supply input end is electrically connected with the output end of the uninterruptible power supply through the gating module, and can directly supply power to the load when the gating module is closed; meanwhile, the second mains supply input end can be used for supplying power to the energy storage unit in the uninterruptible power supply, and when the switching-on module is closed, alternating current provided by the second mains supply input end can be converted into direct current through the voltage transformation unit in the uninterruptible power supply, and then the energy storage unit in the uninterruptible power supply is charged.
Therefore, by setting the second mains supply input end as the bypass power supply input of the uninterruptible power supply, the reliability of the power supply system for supplying power to the load can be improved, and the power supply system can still maintain the normal operation of the load through the second mains supply input end even under the extreme conditions of abnormal power supply of the first mains supply input end, excessively low storage capacity of the uninterruptible power supply and the like.

A distributed ups-based power supply system as in claim 3 further comprising a second utility input and a gating module, wherein the second utility input is electrically connected to the ac-output ups via the gating module and is used as a bypass power input to the ac-output ups, the input voltage of the second utility input is consistent with the output range of the ac-output ups, and the output parameters of the ac-output ups follow the input parameters of the second utility input.
5. The distributed uninterruptible power supply-based power supply system of claim 4, wherein the uninterruptible power supply with ac output includes a plurality of the transformer units, the ac outputs of the plurality of transformer units are connected in parallel to supply power to a load, and the energy storage unit is electrically connected to a common dc bus of the plurality of transformer units.
6. The distributed uninterruptible power supply-based power supply system of claim 1, wherein the phase-shifting transformer uses a voltage higher than a voltage required by a load and is converted by the uninterruptible power supply to be supplied to the load.
7. A data center comprising a load, and the distributed uninterruptible power supply-based power supply system of any of claims 1 to 6, the power supply system being electrically connected to the load.
