1. An apparatus comprising:
- an alternator;
an output drive mechanism; and
at least one synchronous inverter including a plurality of switches connected between the alternator and the output drive mechanism,wherein the at least one synchronous inverter includes a first synchronous inverter associated with a first wheel of a vehicle and a second synchronous inverter associated with a second wheel of the vehicle, wherein the first wheel or the second wheel is coupled to the output drive mechanism,wherein a force from the first wheel causes power to flow from the first synchronous inverter to the second synchronous inverter to the second wheel.

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.
