Circuit arrangement for a converter, method for operating an inverter and aircraft with such a circuit arrangement

摘要

The invention provides a circuit arrangement of an inverter (1) for the electrical supply of a polyphase electric motor (2). The arrangement comprises: - a plurality of DC-powered (+ DC, -DC) phase intermediate circuit circuits (13) and a plurality of inverter circuits (5) electrically connected to a respective phase intermediate circuit (13), - one phase intermediate circuit (13) and one inverter circuit for each phase (5), which together form a commutation cell (14). An aircraft with such a circuit arrangement as well as an operating method with such a circuit arrangement are also indicated.
