Abstract: An apparatus includes a controlled field alternator or utility source of electrical power, a conversion device, and a controller. The conversion device includes a first power input associated with a first power source, a second power input associated with a second power source, and circuitry configured to perform a first conversion of power from a first format from the first power source to a second format for charging the second power source and perform a second conversion of power from the second format for the second power source to a third format for supplying a load.

Abstract: A system and method for paralleling generators is described. A timing signal indicative of a waveform reference point of at least a first generator of the generators is received at a second generator. The receiving generator determines a closing time for a second generator breaker associated with the second generator in response the timing signal from the first generator. The first generator breaker and the second generator breaker, or an aggregated generator breaker is closed to a bus at the closing time.

Abstract: A system for supplementing a fixed fuel source for an engine includes a motor-generator set connected to a mechanical load device and a controller. The motor-generator set includes a motor and a generator. The engine is configured to provide a first torque from a fixed fuel source from an independent variable flow input. The fixed fuel source is independent of the engine and set external to the engine. The mechanical load device is driven by the engine and configured to require a second torque defined by an independent flow device. The controller is configured to compare the first torque and the second torque, provide a first control signal to the motor to provide power to the engine when the second torque exceeds the first torque and provide a second control signal to the generator to draw power from the engine when the first torque exceeds the second torque.

Abstract: A system and method for an interleaved inverter including a set of module circuits and an inverter controller. The module circuits include multiple switches. The inverter controller is configured to assign a first phase shift value to each of the module circuits during a normal mode of operation and assign a second phase shift value to at least one of the module circuits during a failure mode of operation. The second phase shift value is greater than the first phase shift value.

Abstract: A circuit for minimizing energy provided to a ground fault includes a source, a multiple switches, an output filter, and a controller. The switches include a first side pair of switches and a second side pair of switches configured to provide an output signal based on the source. The output filter includes one or more energy storage elements coupled to the first side pair of switches or the second side pair of switches. The controller is configured to receive a ground fault signal that indicates a fault has occurred and configured to generate a switch signal for the switches for a minimum energy state of the output filter and in response to the ground fault signal.

Abstract: A generator system for operation of at least one generator and at least one breaker includes an interface, a database, and a generator controller. The interface is configured to receive an architecture for the generator system. The database includes at least one generator parameter and at least one breaker parameter. The generator controller is configured to determine generator layouts from the architecture for the generator system. The generator controller determines a generator system command based on a comparison of the generator layouts, the at least one generator parameter, and the at least one breaker parameter.

Abstract: An electric machine includes a stator, a rotor, and magnets. The stator includes multiple flux members having ferrous material. The rotor is configured to rotate relative to the stator and spaced from the stator by an air gap. The magnets are rigidly mounted to the flux members of the stator. At least a first magnet and a second magnet of the magnets includes an elongated axis parallel to a radius of the rotor and a minor axis perpendicular to the elongated axis, and a first pole of the first magnet having a first polarity and positioned along the minor axis to face a first pole of the second magnet having the first polarity.

Abstract: A generator system may include redundant control. The generator system may include any combination of redundant controllers, redundant communication paths, or other redundant control. A generator system may include an electrical bus, a first generator controller, and the second generator controller. The first generator controller may control a first generator breaker for connecting a first generator to the electrical bus and configured to control an external breaker for selectively connecting the electrical bus to an external source. The second generator controller may control a second generator breaker for connecting a second generator to the common bus and configured to control the external breaker for selectively connecting the electrical bus to the external source.

Abstract: An apparatus includes a controlled field alternator or utility source of electrical power, a segmented waveform converter, and a controller. The source of electrical power is configured to generate a polyphase signal. The synchronous inverter includes multiple switches connected between the polyphase signal of the source of electrical power and an output filter. The controller is configured to provide a control signal for the switches based on measured electrical quantities associated with the output filter and may provide a field control signal to the controlled field alternator. The apparatus may be applied to a vehicle, a lawnmower, a zero turn radius lawnmower, or another type of machine.

Abstract: An apparatus for predicting a load event in a generator system or a method for predicting the load event in the generator system may include monitoring output data associated with an electrical output of a generator, monitoring external sensor data associated with the generator, detecting a load event for the generator from the output data, identifying a subset of the external sensor data that preceded the load event from the output data, performing an analysis of the subset of the external sensor data, and determining a load event characteristic from the analysis, the load event characteristic indicative of a subsequent load event for the generator.
