Abstract: An assembly according to an embodiment of the present disclosure includes, among other things, a synchronous machine including a rotating portion and a stationary portion, the rotating portion including at least one rotating diode coupled to a field winding, and the stationary portion including a stator winding and an exciter winding. A control unit includes a first gate and a second gate. The exciter winding is connected in series to the first gate and the second gate during a first operating mode to energize the exciter winding. The exciter winding is electrically connected in series to a first gate but is electrically disconnected from the second gate in a second, different operating mode to electrically disconnect the exciter winding from an exciter energy source. A method of operating a synchronous machine is also disclosed.

Abstract: A voltage driver includes a voltage input, a voltage regulation controller including an on/off input. The voltage regulation controller is configured to control a switching converter in a first mode, a second mode, and at least one additional mode. The switching converter is configured to operate as an open pass switch in the first mode, is configured to operate as a closed pass switch in the second mode, and is configured to operate as an overcurrent and overvoltage protection switch in the at least one additional mode. A discrete output driver control and monitoring circuit can be used to control the switching converter. The output driver control and monitoring circuit includes a controller coupled to a communication bus and is configured to provide high level control instructions to the communication bus.

Abstract: A power quality monitor (PQM) module includes a solid-state semi-conductor switch having a voltage input, two signal inputs and two voltage outputs. A voltage input line is electrically connected to the voltage input. A PQM signal input line is operatively connected to at least one of the two signal inputs. A voltage output line is electrically connected to one of the two voltage outputs to provide power to a load. A method of controlling a GCB includes opening a solid-state semi-conductor switch when a PQM signal is powered at a first logic voltage. The method includes closing the solid-state semi-conductor switch when a PQM signal is powered at a second logic voltage lower than the first logic voltage to allow a voltage from a GCU to go to the GCB.

Abstract: A system including a generator and a controller. The generator includes a permanent magnet generator (PMG), and an exciter. The controller manages operations of the generator. The controller includes an alternating current to direct current (AC-to-DC) converter that generates a direct current (DC) voltage, an exciter drive that provides a DC current to the exciter of the generator using the DC voltage created by the AC-to-DC converter in accordance with the control signal, and a regulator controller that drives the active AC-to-DC converter.

Abstract: A power system includes an integrated drive generator (IDG) including an exciter field winding. A generator control unit (GCU) includes exciter drive circuit configured to electrically energize the exciter field winding, and a main stator configured to output voltage to at least one electrical load. The exciter drive circuit includes a dynamic flyback unit configured to selectively operate the exciter drive circuit between a first mode and a second mode different from the first mode based on a change in the at least one electrical load.

Abstract: A system includes a generator control unit (GCU). The GCU includes a saturable reactor and a rectifier. Each of the saturable reactor and the rectifier has a separate input to receive AC power from a separate respective permanent magnet generator (PMG). A method includes supplying AC power from a first permanent magnet generator (PMG) of a generator to a saturable reactor of a generator control unit (GCU) that is operatively connected to control the generator. The method includes supplying AC power from a second PMG to a rectifier of the GCU, wherein the first PMG supplies a lower AC voltage to the saturable reactor than the second PMG supplies to the rectifier.
