Embodiment Construction
[0033] Such as Figure 2-6 As shown, a method for realizing balanced parallel connection of electronic switching devices includes:
[0034] (1) Connect the positive and negative inputs to two water-cooled busbars respectively to form a positive input water-cooled busbar and a negative input water-cooled busbar. The two water-cooled busbars are arranged in parallel; the water-cooled busbars are water-cooled aluminum busbars.
[0035] (2) Composite busbars are respectively arranged on the positive input water-cooled busbar and the negative input water-cooled busbar, wherein the composite busbar is composed of the same two layers of copper plates stacked alternately, and an insulating layer is set between the two layers of copper plates to insulate and isolate the two One-layer copper plate, the insulating layer is PET insulating paper; the two copper plates are respectively copper busbars, and the copper busbars are copper plates with opposite polarities after conducting electri...
