Abstract: An apparatus and method for allowing continuous operation of a generator control unit (GCU) despite a ground fault short circuit is disclosed. More specifically, a generator control unit (GCU) that maintains an isolated power pass domain in a completely floating set up with respect to the ground referenced control domain is used to allow continuous operation of a generator control unit (GCU) even when an internal wiring such as a permanent magnet generator wire or a generator field coil wire comes in contact with the chassis due to failure of the insulation. In addition, the apparatus and method also utilizes a high ohmic resistor as the only connection between the isolated power pass domain and the ground referenced control domain to control the voltage spike that occurs during a ground fault short circuit. Finally, the apparatus and method is also capable of detecting the occurrence of a ground fault short circuit by utilizing a ground fault detection to detect a disbalance current passing through a high ohmic resistor.

Abstract: A generator control unit for fast field discharge of a field coil is disclosed. The generator control unit comprises a control domain for detecting an excessive generator output voltage, a buck regulator with a feedback pin fed from the control domain, and an over-voltage protection switch connected in a field coil return path which is bypassed by a voltage limiting device. The control domain receives a point of regulation voltage feedback and upon detection of an over-voltage, emits a disable signal to cause the buck switch shut off along with the over-voltage protection switch. Thus dual breaking points are created at two ends of the field coil to dissipate the field charge quickly through the voltage limiting device. When the buck switch experiences a shorting failure, the over-voltage protection switch provides a second breaking point to allow the field discharge through the voltage limiting device, thereby controlling the field discharge with directly controlled over-voltage protection switch.
