Abstract
A circuit for pre-charging an intermediate circuit having a positive branch and a negative branch includes: a first controllable energy source, a second controllable energy source, the first control energy source and second controllable energy source being looped in series between the positive branch and the negative branch on the output side, a suppression unit, the suppression unit being looped between a connection node of the output of the first controllable energy source and the output of the second controllable energy source and a reference potential, and a controller. The controller is connected to the first energy source and the second energy source for signaling purposes and is configured to actuate the first energy source and the second energy source in order to generate an output signal pattern in order to pre-charge the intermediate circuit.
