A modular switch for an electrical converter, an electrical converter as well as a method for operating an electrical converter

摘要

It is a modular switch (10) for an electrical voltage system converter described. The modular switch (10) is provided with a first series circuit consisting of a first controllable power semiconductor component (v1) and a first diode (d1) and with a second series circuit consisting of a second diode (d2) and a second controllable power semiconductor component (v2) provide. The connection point between the first power semiconductor component (v1) and the first diode (d1) forms a first terminal (11) and the junction point of the second diode (d2) and of the second power semiconductor component (v2) forms a second connection (12) of the modular switch (10, 20). It is a capacitor (c) is provided, whereby the first series circuit and the second series circuit and the capacitor (c) are connected in parallel to one another.
