Inverter comprising a device for the mutual alignment of three components

A method for assembling an inverter, said method comprising the steps of:

• providing a casing comprising two elongate centering elements extending parallel and arranged at a distance from one another, and rigidly connected to said casing;
• mounting a busbar assembly, with the two elongate centering elements passing through two calibrated holes in said busbar assembly, and securing the busbar assembly to the casing;
• installing power modules in the casing, said power modules comprising male connectors;
• mounting a connector guide around said male connectors to keep the male connectors in a given orientation relative to one another;
• said two elongate centering elements passing through calibrated holes in said connector guide,
• mounting a screen, said screen comprising calibrated orifices, said two elongate centering elements passing through the calibrated orifices,
• mounting a circuit board, the two elongate centering elements passing through calibrated holes in said circuit board, thereby aligning said circuit board with respect to the connector guide and with respect to the busbar assembly, so that the male connectors of the power modules are received in the corresponding female connectors of the circuit board and so that the current sensors rigidly connected to the circuit board are positioned in an air gap of a ferromagnetic element of the busbar system.
