[0038] It should be noted that the primary output busbar 6 is directly connected to the output terminal of the power supply and serves as the basic output section. The secondary output busbar 7 is used to connect multiple power supplies with the same current intensity in parallel, so as to multiply the output current intensity on them. In this embodiment, the power supply assembly 5 includes one primary power supply 1, one secondary power supply 2, and two tertiary power supplies 3. Therefore, the secondary output busbar 7 is only connected to the third output busbar 31 on the output side of the two tertiary power supplies 3 to obtain a higher output current intensity.
