Abstract
Described is an electric circuit which is intended, in particular, for the testing of a power producer in a wind power plant. The power producer is connected to a terminal point and is provided with a converter circuit which can be used to influence a voltage that is present at the terminal point. Also provided is a series connection configured with a choke coil and a first switch and connected to the terminal point. In at least one embodiment, a control and/or regulating system is provided for influencing, in a time-synchronized manner, on the one hand the converter circuit, such that the voltage at the terminal point transitions to a desired value and, on the other hand, the closing of the first switch.
