摘要： The invention relates to a regulator device for charging a battery by an alternator that delivers a rectified voltage including a ripple component. The device is of the type comprising a regulator circuit acting on the mean value of the rectified alternator voltage and a regulator circuit acting on the voltages of the positive peaks of the ripple component.

摘要： A control member is connected to an air-conditioning computer and it receives therefrom a signal for triggering defrosting of the windshield. Switch-over means are connected to the rectified output of the alternator and connect the output either to the network for distributing electrical energy at the nominal voltage of the vehicle battery, or else to a network for feeding the electric windshield. The control member is constituted by a logic unit delivering a plurality of sequential control signals. These signals include at least one signal for controlling de-excitation of the inductor of the alternator, which signal is delivered to the excitation regulator, and a switchover control signal for controlling the switchover means. Raised-voltage regulation is inhibited so long as the battery is connected to the rectified output of the alternator and it is enabled when the windshield is connected to the rectified ouptut of the alternator. The invention is applicable to power supply circuits in motor vehicles, including heavy goods vehicles, utility vehicles, and private cars.
