摘要： In accordance with an embodiment, a circuit includes voltage supply terminals configured to provide an AC output voltage, at least two converter units, and a control circuit. Each converter unit includes input terminals configured to be connected to an electrical charge storage unit, output terminals, and a switch arrangement connected between the input and output terminals. The switch arrangement is configured to receive a control signal, and provide an output voltage having a duty-cycle dependent on the control signal. The control circuit is configured to provide a set of parameter sets that are dependent on a desired output voltage waveform, define a duty-cycle, and generate the control signals for the at least two converter units such that one parameter set is selected from the set of parameter sets is assigned to one converter unit, and the assignment of parameter sets to the converter stages varies over time.
