A power converter includes a DC/AC converter with input terminals and output terminals. A DC/DC converter includes input terminals for receiving a DC input voltage and output terminals for providing a DC output voltage. The output terminals are coupled to the input terminals of the DC/AC converter. The DC/DC converter also includes a control circuit that is configured to control an output current of the DC/DC converter dependent on a reference signal. The reference signal has a frequency that is dependent on a frequency of the AC output voltage.
