The invention relates to a voltage transformer (1) for transformation between a direct voltage at a direct voltage gate (2) and a single-phase or multi-phase alternating voltage at an alternating voltage gate (3) by temporal clocking of an electronic switching unit (4), via which each phase (3a-3c) of the alternating voltage gate (3) can be connected either to the positive pole or to the negative pole of the direct voltage gate (2), wherein the positive pole and/or the negative pole of the direct voltage gate (2) is connected via at least one capacitor (5, 5a, 5b) to a ground connection (7), wherein the ground connection (7) can be connected to an external ground (7a), and wherein the connection between the capacitor (5, 5a, 5b) and the ground connection (7) is guided via at least one switch element (6, 6a, 6b). The invention also relates to an electric powertrain (10) for a motor vehicle (100). The invention further relates to a motor vehicle (100) having the electric powertrain (10).
