Zusammenfassung:	The power sub-assembly (3) for a micro-hybrid system (1) in an automobile includes a AC-DC converter (8) with a transistor bridge (13), an energy storage device (10) and a power bus (9) including at least two substantially symmetrical and parallel conductors (22). The conductors (22) include respective substantially planar surfaces (23, 23′) facing each other. The power bus integrated in the power subassembly allows for a parasitic inductance that is by far lower than that of the standard cables in power subassemblies of the prior art, particularly in order to avoid overvoltage at the terminals of the transistors in the AC-DC converter.
