Signaling method and device for impaired function of an electronic power system in a multiple-phase alternator

摘要

The signalling method is implemented in an electronic power system (6) of a multiple-phase alternator. The system (6) is of the type comprising a set of rectifiers (5) capable of rectifying the voltage of phases (Ph1, Ph2, Ph3, Ph4, Ph5, Ph6) produced by the alternator, and a control assembly (2, 3) capable of controlling an excitation current from the alternator, of monitoring the conformity of at least one current characteristic of at least one (Ph) of the voltage of phases (Ph1, Ph2, Ph3, Ph4, Ph5, Ph6) in relation to a nominal characteristic, and of signalling any non conformity. In accordance to the method of the invention, the non conformity of at least one current characteristic of at least one (Ph) of the voltage of phases (Ph1, Ph2, Ph3, Ph4, Ph5, Ph6) is simulated in case of impaired function of at least one of the rectifiers (5). The invention thus permits the use of signalling means provided in an existing regulator to signal additional impaired functions which were not initially processed by the signalling means.

1. A method of signalling anomalous operation of an electronic power system (6) of a multiple-phase alternator (11), said method comprising:
rectifying phase voltages (Ph1, Ph2, Ph3, Ph4, Ph5, Ph6) produced by said alternator (11) by a set of rectifiers (5) each rectifier comprising a metal-oxide-semiconductor field -effect transistor (MOSFET) and a control circuit coupled to said MOSFET, wherein each control circuit has an output and each output of each control circuit of the set of rectifiers is connected in common to a single connection coupled to a regulator system (2,3); controlling an excitation current of said alternator (11) by said regulator system (2, 3); monitoring conformity of a standard characteristic of at least one of said phase voltages (Ph1, Ph2, Ph3, Ph4, Ph5, Ph6) to a nominal phase voltage (Ph) by said regulator system (2, 3), wherein the conformity of the standard characteristic is based on an output of the single connection; and signaling a non-conformity of said standard characteristic of at least one of said phase voltages (Ph1, Ph2, Ph3, Ph4, Ph5, Ph6) when an offset voltage is detected at the output of the single connection, wherein the non-conformity is signaled by a lamp (3) of the regulator system (2,3).
