Abstract
Disclosed is an electric circuit, in particular for a medium voltage power converter. The circuit has at least four semiconductor switches which form a series connection and which are connected to poles of a direct current voltage (Ud). A diode is connected in parallel in an inverse direction to each semiconductor switch. A capacitor is connected in parallel to the two semiconductors in the middle of the series connection. The circuit is provided with a pole of an output potential (Ua) which is connected centrally in the series connection. The circuit has a control device for successively controlling the semiconductor switches. The time interval between the transition of two of the semiconductor switches into their respective controlling states is minimal.
