The converter (10) has an alternating-current (AC) output (22) attached with a drive motor (12) over an inverter circuit (24), and coupled with a direct-current (DC) voltage terminal (16) for attaching a traction battery (14). An AC input (32) is coupled with the DC voltage terminal over a rectifier circuit, where the AC input is different from the AC output. The rectifier circuit comprises rectifying units (58, 60) that are provided with inductive circuit elements (50, 52). The inductive circuit elements are formed by a secondary coil (46) of a transformer (44) and a primary coil (42). Independent claims are also included for the following: (1) a motor vehicle (2) a method for operating an electric drive motor of an electric vehicle.
