Title: USE OF A CONTROL SYSTEM OF A POLYPHASE ROTARY ELECTRIC MACHINE COMPRISING PHASE SHORT-CIRCUIT MEANS, AND USE OF THE CORRESPONDING ROTARY ELECTRIC MACHINE
Abstract:
The polyphase rotary electric machine in which the invention is implemented comprises phase short-circuit means (15, 18) included in a control system (10). The machine is fitted in a motor vehicle, operates as a generator and is connected to an on-board electric network (2). The phase short-circuit means short-circuit at least one phase winding when a DC voltage measurement (B+) of the network, regulated by a regulator device, exceeds a predetermined threshold value and a phase current 15 in the phase winding is cancelled out and changes direction. According to the invention, the control system limits an overvoltage on the network due to an event other than load shedding.
