摘要:
The invention relates to a mixed electrical circuit with inverter function and AC/DC converter function comprising: four arms in parallel exhibiting common ends (D, E), these including an accumulator arm (24) equipped with a capacitor (C1) and three switch arms (21, 22, 23) each equipped with two pairs of chopper switches/diodes (Ta1, Da1 - Tc2, Dc2) connected in series, on either side of a midpoint (A, B, C); at least one inductor (Ec); at least three relay switches (R1, R2, R3) for toggling from the inverter mode to the AC/DC converter mode and vice versa; and a drive unit for said relay switches, said unit being equipped with means for measuring the intensity (i ph1 , i ph2 , i ph3 ) of the current passing through each phase circuit (30a, 30b, 30c) and the potential difference (V1) across the terminals of said capacitor. According to the invention, the drive unit is adapted for deducing the states of said relay switches directly from said intensities and from said potential difference.
