Power converter circuit with AC output

摘要

A power converter circuit includes output terminals configured to receive an external voltage. A series circuit with a number of converter units is connected between the output terminals of the power converter circuit. Each converter unit includes input terminals configured to be coupled to a DC power source and output terminals configured to provide an output current. At least one converter unit of the converter units includes a signal generator configured to receive a synchronization signal and to generate a continuous synchronization signal from the synchronization signal. The power converter circuit can be operated in a normal operation mode. In the normal operation mode, the at least one converter unit is configured to regulate generation of the output current such that a frequency and/or a phase of the output current are dependent on the continuous synchronization signal.
