Electrical system of a vehicle with electrical traction

摘要

An electrical system (11) of a vehicle (1) with electrical traction provided with a reversible electric machine (8) that can be mechanically connected to drive wheels (3); the electrical system (11) has: a low voltage storage system (14); an electronic power converter (15) having a positive pole (21) and a negative pole or electrical ground (23) that are connected to the low voltage storage system (14) through a first electrical cable (18) having a large section; and an electronic control unit (17) that controls the electronic power converter (15) and has a positive pole (24) and a negative pole or electrical ground (25) that are connected to the low voltage storage system (14) through a second electrical cable (19) having a small section; wherein the electrical ground (23) of the electronic power converter (15) is connected to the electrical ground (25) of the electronic control unit (17) only through an impedance having value not lower than 100 Ohm.
