Abstract

A method for operating a circuit arrangement is provided. The method may include coupling a second connection of a control device to a connection that provides an alternating signal during operation of the circuit arrangement; in the control device: generating a trigger signal for the control electrode of the mode switch that is correlated with the sum signal from the signal at the connection for providing an alternating signal and the control signal; and providing the trigger signal at the output of the control device.
