A converter arrangement (30) comprises a first chopper circuit (40a) for connecting a positive input (32a) or a neutral point (50) with a positive output (34a), wherein the first chopper circuit (40a) comprises a first switch arrangement (42a), a first inductor (44a) and a first capacity (46a), wherein the first switch arrangement (42a) is adapted for connecting the first inductor (44a) with the positive input (32a) or with the neutral point (50), the first inductor (44a) interconnects the first switch arrangement (42a) with the positive output (34a) and the first capacity (46a) interconnects the positive output (34a) with the neutral point (50). The converter arrangement (30) further comprises a second chopper circuit (40b) for connecting a negative input (32b) or the neutral point (50) with a negative output (34b), wherein the second chopper circuit (40b) comprises a second switch arrangement (42b), a second inductor (44b) and a second capacity (46b), wherein the second switch arrangement (42b) is adapted for connecting the second inductor (44b) with the negative input (32b) or with the neutral point (50), the second inductor (44b) interconnects the second switch arrangement (42b) with the negative output (34b) and the second capacity (46b) interconnects the negative output (34b) with the neutral point (50). The converter arrangement (30) further comprises an overvoltage protection device (52) adapted for short-circuiting the positive output (34a) and the negative output (34b), when an overvoltage is measured between the positive output (34a) and/or the negative output (34b) and the neutral point (50, 54).
