<p>A power MOS voltage regulator for recharging batteries of motor vehicles; a voltage generator (10) is selectively connected to a battery (BA), respectively to an earth by means of a controlled rectifier bridge. The rectifier bridge comprises a Schottky diode D3 connected between each phase winding (A, B, C) of the generator (10) and the positive terminal of the battery (BA), and a power MOS transistor (T1) branched between the phase winding (A; B; C) and the earth; a control electrode (G) of the power MOS transistor (T1) is driven by a control circuit (12) for controlling the charging state of the battery (BA), to enable the changeover of the power MOS transistor (T1) between a conductive state (ON) and a non conductive state (OFF), and vice versa, when the voltage of the phase winding (A; B; C) is zero. <IMAGE></p> |
