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.
