Abstract
A control device (2′″) for an AC-DC current converter associated with a polyphase synchronous rotary electrical machine. The AC-DC current converter contains, for each phase, a branch of two power switches in series, known as high and low (25). The control device (2′″) contains means of generating a signal (θ(t)) representing the angular position of the rotor. The control device contains one or more digital tables (20 H, 20 B) addressed by the signal of the angular position of the rotor (θ(t)) and delivering at their outputs binary control signals (200 H- 202 H, 200 B- 202 B), each controlling one branch of power switches (25).
