With continued reference to fig. 4a to 5, the first terminals 311 and the second terminals 312 are staggered on the power input board 310.

When the power supply 30 is the three-phase ac power supply 31, the first terminal 311 is electrically connected with the live wire interface L, the second terminal 312 is electrically connected with the neutral wire interface N, and the first terminal 311 and the second terminal 312 are staggered to avoid mutual interference between different live wire interfaces L.

With continued reference to fig. 7a, when the power supply 30 is a three-phase ac power supply 31, the shorting switch 316 is closed to electrically connect the plurality of second terminals 312. Therefore, the neutral line interface N in the three-phase ac power supply 31 is only required to be electrically connected with one of the second terminals 312, so that the wiring between the three-phase ac power supply 31 and the power supply input board 310 is simplified.

Therefore, the negative electrode interface 32b of the hvdc power source 32 is only required to be electrically connected with one of the second terminals 312, thereby simplifying the wiring between the hvdc power source 32 and the power supply input board 310.

With continued reference to fig. 7c, in the case where the number of high-voltage dc power sources 32 is set to a plurality, the shorting switch 316 is opened to electrically disconnect the plurality of second terminals 312. Thus, a different second terminal 312 may be used to electrically connect with the negative interface 32b of a different high voltage dc power supply 32 to form a power supply loop with the different high voltage dc power supply 32.

In the following, a specific closing or opening manner of the plurality of shorting switches 316 will be described by taking the three-phase ac power supply 31 as an example of the power supply 30.

When the plurality of shorting switches 316 are required to be opened or the plurality of shorting switches 316 are required to be closed, only the shorting switch controller 317 is required to be operated, thereby improving the efficiency of the operator when replacing the power supply 30.

Next, a process of converting the high voltage direct current into the set voltage or converting the alternating current into the set power by the power module 320 will be described.
