1. A method for operating an AC fast charger device, the method comprising:
provisioning gating signals for controlling operation of control operating characteristics of an AC/DC converter front-end circuit, a first traction inverter, and a second traction inverter that, when applied to one or more switching gates of the first traction inverter and the second traction inverter, shape an AC current flowing into the AC/DC converter front-end circuit from an AC power source and deliver power to a first energy storage device coupled to the first traction inverter and an electric motor and a second energy storage device coupled to the second traction inverter and the electric motor;
wherein the AC/DC converter front end circuit is an on-board rectifier connected across a differential connection of the first traction inverter and of the second traction inverter such that the first energy storage device and the second energy device are indirectly series connected through the first traction inverter and the second traction inverter and the motor; and
wherein the gating signals regulate a direction of power between at least one of the first energy storage device and the second energy device and the power source.
