1. An apparatus for voltage equalization in square-wave voltages of electric motors, the apparatus comprising:
a terminal board circuit wherein phases U, V, and W each comprises input and output cabled conductors summing to at least 6 cables; and
a bridge between two of the at least six cables connecting two or more of the at least 6 cable inputs and outputs;
wherein the bridge is partially conductive such that its electrical resistance markedly reduces above a threshold value;
wherein the partial conductivity results from filler particles in an embedding matrix determining a reduction of the resistance in the bridge above the threshold value.
