Abstract

A propulsion circuit for a vehicle includes an engine, a generator, a power rectifier, a direct current (DC) bus, a propulsion battery system, and at least one converter. The generator is coupled to the engine and configured to receive an input from the engine, and to provide an alternating current (AC) output. The power rectifier is configured to receive the AC output from the generator and provide a DC output responsive to receiving the AC output. The DC bus is coupled to the rectifier. The propulsion battery system is coupled to the DC bus. The at least one converter is configured to convert a direct current to an alternating current, and is coupled to the DC bus. Further, the propulsion circuit includes at least one charging component that is configured to selectably provide a charge to the battery system via at least one of the at least one converter.
