Claim 10:
11. A circuit arrangement for regulating a clocked power converter which has an input for inputting an input power and an output for outputting a regulated output power, wherein the circuit arrangement comprises:
a control loop optimized for regulation to a specified continuous output power; and
at least one first and one second input for inputting target values and a regulator;
at least one operational amplifier as part of the control loop, having a first, non-inverting input and a second, inverting input, from the output of which a compensation network as part of the control loop runs to one of its inputs, wherein the compensation network has a third input for a measurement signal of an output power to be regulated, wherein the third input forwards the measurement signal to the first or second regulating input via a second series impedance;
wherein the first input is configured to input a signal for a first target value of the average of the output power to be regulated and forwards this signal to one of the inputs of the operational amplifier via a first series impedance;
wherein the second input is configured to input a signal for the second target value of a waveform for the output power to be regulated, wherein the circuit arrangement is configured to forward the signal for the second target value to one of the inputs of the operational amplifier via a DC current-blocking high-pass filter.
