Abstract: A system includes an excitation system configured to regulate one or more outputs of a power generating system. The excitation system includes a power conversion module (PCM). The PCM includes a direct current (DC) link, a plurality of insulated gate bipolar transistors (IGBTs) configured to generate an output to the system, and a nonlinear resistor configured to limit a voltage of the DC link to a predetermined threshold.

Abstract: An electrical system includes an electrical circuit having a plurality of current paths and a plurality of switches for directing current to the plurality of current paths. A sensor senses a current or voltage in the electrical circuit. A processor connected to the sensor receives sensor data corresponding to the current or voltage in the circuit. The processor is configured to determine a location of a loose connection in the electrical circuit based on the current or voltage data and a switching sequence of the plurality of switches.

Abstract: Embodiments provide systems and methods for controlling electronic circuitry. A system can include at least a first controller and a second controller and at least one power electronic circuitry module. The first controller can be in electrical communication with the power electronic circuitry module via a first high-speed serial link (HSSL). The second controller can be in electrical communication with the power electronic circuitry module via a second HSSL.

Abstract: A regulating system can include a first controller configured to receive analog input and discrete input, a second controller communicatively coupled to the first controller, and configured to receive analog input and discrete input, a selector communicatively coupled to the first controller and second controller and configured to select either one of the first controller and the second controller as a master for the regulating system and state logic residing on each of the first controller and second controller to determine which of the first and second controller is the master.

Abstract: A flux coil system has a first member having a first surface and a first flux coil being disposed in the first member. The flux coil has a first current flowing conduit having a second surface. When current traverses through the first current flowing conduit a first magnetic field is induced. The first surface is adjacent to the second surface such that the first flux coil is in the first magnetic field so that a signal is developed corresponding to the first magnetic field.

Abstract: Grouped gating control logic allows for one or more inputs in a group to be active at any given time. Once an input signal in a group is active, all other pulse trains received in the same group can be locked out. Thus, by using a finite state machine to control gate pulses, the noise margin of the gating unit can be regulated and an extra level of protection is available should one of the input gating signals be defective.
