ABSTRACT:
A regulator for a brushless synchronous alternator that includes a rotary exciter having a stationary excitation inductor. The regulator includes, in combination, a power stage connected to the alternator, an analog regulator circuit connected to the power stage to regulate a plurality of parameters, a digital regulator circuit connected to the power stage to regulate a plurality of parameters, and a control circuit designed to enable the regulator unit to operate in two modes: a normal mode in which the regulation function is performed by the digital regulator circuit and a fault mode in which the regulation function is performed by the analog regulator circuit. The digital regulator circuit is isolated from the alternator, in particular mechanically and/or magnetically, and is connected to the control circuit via insulated electrical connections.
