vehicle-based rotating electrical machine with a rectifier module, which is provided with a fault detecting function described

摘要

A plurality of the rectifier modules, can in a rotating electrical machine are arranged, are electrically connected to one another. Each of the rectifier module has a switching unit, the circuits of an upper and a lower branch, each of which a switching element (50, 51), a control unit (100), which controls the switching element, in order to be a and a detection unit (140, 141, 150, 151, 123), a fault in the case of the switching element is detected, a signal transmitters (164), an error signal to another rectifier module sends the detection unit, when the error is detected, a signal receiver (162), which the error signal which, by means of the other rectifier module has been sent, and a processing unit (123) to a switching element, which the error, and the circuit of the upper branch or the circuit of the lower branch a switched- has in itself, and the other switching element, when the detection unit out-turn the error is detected, or of the signal receiver receives the error signal.
