Multi-level multi-function inverter

A system for charging a battery of a vehicle, comprising:

• an electric motor couplable to a charging station;
• a capacitor-clamped multi-level inverter that includes a first leg having a first set of switches and a first AC terminal coupled to the electric motor, a second leg having a second set of switches and a second AC terminal coupled to the electric motor and a third leg having a third set of switches and a third AC terminal coupled to the electric motor, wherein the capacitor-clamped multi-level inverter is configured to couple the electric motor to the battery;
• processor configured to:
• connect one of the third AC terminal of the third leg of the capacitor-clamped multi-level inverter and a neutral point of the electric motor to the charging station;
• and
• control at least one of the first set of switches to control a first current through the first AC terminal of the first leg and the second set of switches to control a second current through the second AC terminal of the second leg to charge the battery via the charging station through the electric motor.
