The arrangement relates to a voltage transformer for transformation between a direct voltage at a direct voltage gate and a single-phase or multi-phase alternating voltage at an alternating voltage gate by temporal clocking of an electronic switching unit, via which each phase of the alternating voltage gate can be connected either to a positive pole or to a negative pole of the direct voltage gate. The positive pole and/or the negative pole of the direct voltage gate is connected via at least one capacitor to a ground connection. The ground connection can be connected to an external ground, and the connection between the capacitor and the ground connection is guided via at least one switch element. The arrangement also relates to a motor vehicle having the electric powertrain. A diagnosis arrangement includes a voltage source and monitors the state and function of a switching element.
