Circuit for Pre-Charging an Intermediate Circuit, and Electric System

A circuit for pre-charging an intermediate circuit, wherein the intermediate circuit has a positive branch and a negative branch, comprising:

• a first controllable energy source,
• a second controllable energy source, wherein the first controllable energy source and the second controllable energy source are looped in, on the output side, in series between the positive branch and the negative branch,
• an interference suppression unit, wherein the interference suppression unit is looped in between a connecting node of the output of the first controllable energy source and of the output of the second controllable energy source and a reference-ground potential, and
• a control device,
• which is connected in a signal-transmitting manner to the first energy source and the second energy source, and
• which is configured to actuate the first energy source and the second energy source to generate an output signal pattern in order to pre-charge the intermediate circuit.
