DISPOSITIF DE REGULATION D'UNE MACHINE ELECTRIQUE TOURNANTE DE VEHICULE AUTOMOBILE, ET MACHINE COMPRENANT CE DISPOSITIF DE REGULATION

摘要

#CMT# #/CMT# The device has an electric autarky system (11) with a voltage maintaining circuit (110) for providing autarky supply voltage (V0) to a digital processing block (9). The electric autarky system includes an autarky controlling circuit (111) to control autarky of the digital processing block according to the amplitude of the autarky supply voltage. The autarky controlling circuit includes a stop unit (12) to stop a clock (5) of the digital processing block when the autarky supply voltage is less than a reference supply voltage (V1) of the digital processing block. #CMT#USE : #/CMT# Device for controlling a polyphase rotary electric machine e.g. alternator and alternator-starter, in a motor vehicle (claimed). #CMT#ADVANTAGE : #/CMT# The design of the electric autarky system enables improving robustness of the device against power line disturbance in power supplies of the device and against transitory disturbances transmitted by an onboard network of the vehicle. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a circuit diagram representing a digital processing block and an analog control block in a polyphase rotary electric machine controlling device of a motor vehicle.
