Further, the responsibility board 3 Further, a voltage signal jumper line (10) is electrically connected to the first voltage balance line 313, the second voltage balance line milk, and a current signal jumper line 37 is electrically connected to the first current balance line 314, The second current balancing line 324. The power balancing busbars 310, 320 are in fact connected to each other through the voltage signal crossing line % and the current signal crossing line 37, so that the first secondary power unit 12, 22, the second pair The power units 13, 23 are actually sensed and balanced with each other, providing the first sub-power units 12, 22 'the second sub-power units 13, 23 mutually compensating for the output (10), improving stability, and extending the useful life of many excellent effects. The power jumper line 35, the voltage signal jumper line 36, and the current signal jumper line 37 may be a jumper or wire or copper foil or a jumper between the two-phase different busbars or In view of the above, each of the power supplies 1 and 2 includes a first sub-power unit 12, 22 and a second sub-power unit 13, 23, and has a backplane 3 thereon. The plurality of bus bars and the jumper lines enable the output currents of the first auxiliary power unit 12'22 and the second auxiliary power unit 13 and 23 to be collected together, and the output voltage and current can be sensed and adjusted to each other, and can be provided to meet customer requirements. And power supply specifications for future design trends.

Anyone who is familiar with the art, without departing from the spirit and scope of the case, has made some changes and refinements. It should be covered in this case, so the scope of protection of this case is subject to the definition of the scope of the patent application attached. In summary, this case enhances the above-mentioned effects compared with the well-known creations. It should fully comply with the novelty and progressive statutory innovation patent requirements. If you apply in accordance with the law, you are requested to approve the new patent application case. Feeling the virtues.
