| 摘要 |
The invention relates inter alia to a multicell converter (10) having at least one series connection (R1, R2, R3) that comprises at last two switch modules (SM) that are connected in series, and a control unit (30) that is connected with the switch modules (SM), which control unit can actuate the switch modules (SM) in such a way that the multicell converter (10) has a predetermined behavior, wherein each switch module (SM) comprises two half-bridge modules (HBM), respectively, which comprise in each case two switch elements (T11-T12; T13-T14) connected in series comprising in each case a diode (D0) connected in parallel and an electric energy storage device (C) which is connected in parallel to the switch elements (T11-T12; T13-T14) that are connected in series, and wherein the two half-bridge modules (HBM) are connected in series and electrically connected by means of at least one switch element(T15, T15.1, T15.2). According to the invention, the at least one diode (D1), a series connection consisting of two or more diodes and/or at least one switch element are located electrically parallel to the two half-bridge modules (HBM) that are switched in series. |
