Electric generators are described herein. The electric generators include an interior machine formed of an interior rotor and an interior portion of a stator, and an exterior machine substantially concentric to the interior machine. The exterior machine includes: an exterior rotor substantially concentric to the interior rotor, and an exterior portion of the stator. Each of the interior machine and the external machine are driven by an engine to produce a respective current. The described electric generators can be used in diesel electric locomotives.

Various embodiments are described herein for a dual-voltage charging system for electrified vehicles. In one example embodiment, the dual-voltage charging system comprises an integrated active filter auxiliary power module (AFAPM), the integrated AFAPM is applied as an active power filter (APF) to compensate low frequency harmonics in a high voltage (HV) battery charger when the HV battery is charging, and applied as a low voltage (LV) battery charger auxiliary power module (APM) when the HV battery stops the charging and starts to charge the LV battery.
