Abstract
Various embodiments of the teachings herein include an apparatus for voltage equalization in square-wave voltages of electric motors. The apparatus may include: 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. The bridge is partially conductive such that its electrical resistance markedly reduces above a threshold value. The partial conductivity results from filler particles in an embedding matrix determining a reduction of the resistance in the bridge above the threshold value.
