The device comprises a switch (1), three first (21, 22, 23) and three second (31, 32, 33) diodes, whereby the anodes of the diodes (21, 22, 23) are electrically connected to phases A, B, C and the cathodes of said diodes are connected to the first input of the switch (1), the second input of which is connected to the anodes of the diodes (31, 32, 33) the cathode of each of which is electrically connected to the corresponding phase A, B, C through its own inductive element (41, 42, 43), while the cathodes of the diodes (31, 32, 33) and the anodes of the diodes (21, 22, 23) are interconnected to common points having in between a capacitive coupling. |
