Use of an inverter switching arrangement for operating a system with electric drive

An inverter switching arrangement to operate a system with an electric drive, comprising:

• an alternating signal connection to connect a component, and which is configured to operate with an alternating signal,
• a direct signal connection to connect a component, and which is configured to operate with a direct signal,
• an inverter circuit, which couples the alternating signal connection and the direct signal connection to each other,
• wherein the inverter circuit includes at least two phases, which are connected to a first contact of the direct signal connection with a first side and to a second contact of the direct signal connection with a second side, respectively,
• wherein each phase of the at least two phases includes at least two first switching elements connected in series, and each phase of the at least two phases is connected to a respective contact of contacts of the alternating signal connection, via a center tap,
• at least one second switching element associated with each phase of the at least two phases to form a hybrid circuit,
• wherein the at least two first switching elements are semiconductor switches of a semiconductor technology different from a semiconductor switch of a semiconductor technology of the at least one second switching element, and
• at least one control circuit to operate the inverter circuit in a short circuit operation to short-circuit the alternating signal connection by each respective phase of the at least two phases in case of a fault, and to switch the at least two first switching elements and the at least one second switching element in a switching operation.
