Abstract

The control and monitoring data transmission conductors between the control board and the transistor conversion circuit are formed into a flexible flat cable whose intermediate part is wound on a single magnetic circuit to constitute a common mode inductance designed to compensate the disturbances affecting the printed circuit board due to the potential changes of the semi-conductors generated when switching takes place from the conducting state to the blocking state, and vice-versa.
