A circuit board arrangement () for a motor controller in a motor housing () has at least one first populated circuit board (LP) and one second populated circuit board (LP). Contact elements () are plugged together in the plug-in direction(S) in order to produce a detachable electrical connection with the first circuit board (LP). An alignment and guidance device (LP) protrudes from the first circuit board (LP) in the plug-in direction(S) toward the second circuit board (LP). In the assembled state, the contact elements () are completely in the plugged-in state with mating contacts () of the first circuit board (LP). An end-side portion (), of the device (LP), protrudes through a gap () in the second circuit board. The contact elements () protrude from or out of the second circuit board () in different lengths.

Modular circuit board arrangement and method for assembling a circuit board arrangement

The disclosure relates to the operation and a circuit arrangement for a network connection variable with regard to the input voltage (1-phase/3-phase), which is connected using a centre tap (M) between the capacitors (C) via a connecting line to a neutral conductor (N) of an input AC voltage source.
