<p>The circuit has a control unit for generating a drive signal for a semiconducting switch (14) with which both loads (2,3) can be controlled with a control signal (17,18) per load. The control unit has a phase detection device (6) and a logic unit (19) for combining the control signals with the output signal of the phase detection device to determine the drive signal. The circuit arrangement has a control unit for generating a drive signal for a semiconducting switch (14) with which both loads (2,3) can be controlled depending on a control signal (17,18) per load. The control unit has a phase detection device (6), with which a positive or negative phase of the alternating voltage can be detected and that provides an output signal describing the instantaneous phase, and a logic unit (19) for combining the control signals with the output signal of the phase detection device for determining the drive signal. AN Independent claim is also included for the following: (a) an electrical device with an input and an inventive circuit arrangement.</p> |
