Abstract: In accordance with at least one aspect of this disclosure, a controller for an aircraft electrical system includes, a software safe module. In embodiments, the software safe module can be configured to determine whether there was a sudden power failure upon controller initialization, and cause operation of the controller in a software safe mode if there was a sudden power failure such that manual intervention is required to leave the software safe mode to prevent repetitive power failure of the controller.

Abstract: A system comprises a generator control unit (GCU) configured to control a generator. The system includes a first sensor connected to provide feedback to the GCU for generator control. The first sensor is configured to connect to sense at least one of voltage and/or current in a feeder connecting between the generator and a load. The system also includes a second sensor connected to provide feedback to the GCU for generator control. The second sensor is configured to sense at least one of voltage and/or current in a feeder connecting between the generator and the load. The first and second sensors are configured to connect to the feeder apart from one another with feeder impedance therebetween.
