Claim Text:
1. A power converter circuit, comprising: output terminals configured to receive an external voltage; a series circuit with a plurality of converter units, each converter unit comprising input terminals configured to be coupled to a DC power source and output terminals configured to provide an output current, the series circuit connected between the output terminals of the power converter circuit; and a synchronization circuit configured to generate a synchronization signal; wherein the power converter circuit can be operated in a normal operation mode, wherein, in the normal operation mode, the synchronization circuit is configured to generate the synchronization signal dependent on the external voltage, wherein, in the normal operation mode, at least one converter unit of the plurality of converter units is configured to receive the synchronization signal and to regulate a generation of the output current such that a frequency and/or a phase of the output current is dependent on the synchronization signal, and wherein, in the normal operation mode, the synchronization circuit is configured to generate the synchronization signal with a frequency corresponding to a frequency of the external voltage, and with a phase that has a given phase difference relative to the phase of the external voltage.
