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 output of a generator may vary according to the speed of the engine, physical characteristics of the engine, or other factors. A profile for a generator that describes a periodic fluctuation in an operating characteristic for the generator is identified. A field current of an alternator associated with the generator is modified based on the profile for the generator in order to counter variations in the output of the generator.

Abstract: Torque is balanced among generators in a system of parallel generators. Control of the generators may be performed by one or more individual generator controllers or by a centralized controller. The torque on two or more generators is detected. The controller calculates a torque target based on the torque on the two generators or other operating characteristics of the system. The operation of at least one of the generators is controlled based on the torque target.
