Rectifier arrangement

A rectifier arrangement (20) for rectifying an AC voltage (L1, L2, L3;

• HOT1, HOT2) into a DC voltage (DC+, DC−),
• the rectifier arrangement (20) has connections (21, 22, 23, 24), circuit arrangements (31, 32, 33, 34, 35, 36), an interconnection apparatus (26) and an intermediate circuit (50),
• the connections (21, 22, 23, 24) comprise a first connection (21), a second connection (22), a third connection (23) and a fourth connection (24),
• the intermediate circuit (50) has a first line (51), a second line (52) and at least one capacitor (61, 62) between the first line (51) and the second line (52),
• the circuit arrangements (31, 32, 33, 34, 35, 36) each have a first circuit arrangement connection (A) and a second circuit arrangement connection (B), between which a changeover arrangement (92) and a coil (91) connected in series with the changeover arrangement (92) are provided, an order of the changeover arrangement (92) and the coil (91) between the first circuit arrangement connections (A) and the associated second circuit arrangement connections (B) of the circuit arrangements (31, 32, 33, 34, 35, 36) is the same in each case,
• the changeover arrangements (92) are interconnected to the first line (51) and to the second line (52),
• and the interconnection apparatus (26) is designed to enable at least a first configuration and a second configuration,
• in the first configuration, the circuit arrangements (31 to 36) form a first group (31, 32, 35, 36) and a second group (33, 34),
• the first connection (21) and the fourth connection (24) are connected to the circuit arrangements (31, 32, 35, 36) in the first group (31, 32, 35, 36), but not to the circuit arrangements (33, 34) in the second group (33, 34), and
• the second connection (22) and the third connection (23) are connected to the circuit arrangements (33, 34) in the second group (33, 34), but not to the circuit arrangements (31, 32, 35, 36) in the first group (31, 32, 35, 36), and
• in the second configuration at least one of the connections (24;
• 24, 21) is connected to all circuit arrangements (31-36).
