CONVERTER WITH REDUNDANT CIRCUIT TOPOLOGY

摘要

The invention relates to a converter (1) for an aeroplane, comprising an intermediate circuit (3) for providing a DC voltage (18) between a positive line (15) and a negative line (16), at least two rectifiers (7) connected to the intermediate circuit (3) to produce the DC voltage (18) from the AC input voltages and at least two inverters (19) connected to the intermediate circuit (3) to produce AC output voltages from the DC voltage (18). The converter should be configured in a compact manner for aircraft construction. For this purpose, the DC voltage terminals (11) of the rectifiers (7) are connected to a first series circuit (14) and DC voltage terminals (11) of the inverters (19) are connected to a second series circuit (21). The positive line (15) and the negative line (16) of the intermediate circuit (3) are connected on the input side via the first series circuit (14) and on the output side via the second series circuit (21). At least one of the DC voltage terminals (11) comprises a shorting circuit (S1, 9) for short-circuiting terminal contacts (12) via which the DC voltage terminal (11) is connected to the respective series circuit (14, 21).
