BATTERY CHARGER, ELECTRICAL SYSTEM INCLUDING SUCH A CHARGER, ELECTRIC VEHICLE INCLUDING SUCH A SYSTEM

摘要

The battery charger comprises: three inductors (104, 106, 108); three input terminals (BE1, BE2, BE3) connected to an intermediate point respectively of the three inductances (104, 106, 108) and intended to be respectively connected to three phases (PA, PB, PC) of a three-phase network for three phase voltages (VA, VB, VC) are respectively applied to each other; two output terminals (BS1, BS2) between which a battery (102) is to be connected to receive a charging current (i B); for each of the inductor ends, a switching arm (B A ... B F) comprising a first switch (I A1 ... I F1) and a second switch (I A2 ... I F2); a control device (120) of the switches (I A1, I A2 ... I F1, I F2) to pass them in successive configurations. The control device (120) is intended to control the switches (I A1, I A2 ... I F1, I F2) so that, over a certain charging time interval, exactly three first switches (I A1, .. .I F1) are closed at the same time in at least 90% of the successive configurations
