A frequency converter is used for generating at least one frequency converter output voltage a prescribable frequency converter output voltage amplitude and a prescribable frequency converter output voltage frequency for an electric motor. The frequency converter has: a clocked DC/DC converter is designed to generate from an input direct voltage having an input voltage level a DC/DC converter output voltage having a DC/DC converter output voltage level, wherein the DC/DC converter is designed to generate the DC/DC converter output voltage level based on the prescribable frequency converter output voltage amplitude, and a clocked inverter having a number of controllable switches, to which inverter the DC/DC converter output voltage is applied and which actuates the switches with an inverter switching frequency such that the at least one frequency converter output voltage with the prescribable frequency converter output voltage frequency is generated from the DC/DC converter output voltage.
