Abstract
A multiphase power converter circuit includes at least two single phase power converter circuits. Each single phase power converter circuit includes at least one converter series circuit with a number of converter units. The converter series circuit is configured to output a series circuit output current. A synchronization circuit is configured to generate at least one synchronization signal. At least one of the converter units is configured to generate an output current such that at least one of a frequency and a phase of the output current is dependent on the synchronization signal.
