The invention puts forward a bidirectional DC-DC converter for high voltages that is as simple as possible and that entails as few losses as possible. The bidirectional DC-DC converter () converter comprises an input stage () to convert a DC input voltage into first AC voltage, a transformer () to transform the first AC voltage into a second AC voltage, and an output stage () to convert the second AC voltage into a DC output voltage, whereby, in order to provide the first and/or second AC voltage, at least one of the input stages () and/or output stages () comprises a branch of a multi-level converter () with a first number of active first semiconductor switches ().
