A method for discharging a DC intermediate circuit of a converter and a DC intermediate circuit (10) and a converter comprising at least one group of at least two controllable power semiconductor switches (S1, S2, S3, S4, S5, S6, S7, S8) connected in series between two poles (UDC+, UDC-) of the DC intermediate circuit, and means (40) for controlling one or more groups of said at least one group of at least two controllable power semiconductor switches (S1, S2, S3, S4, S5, S6, S7, S8) of the converter to conduct current between the two poles (UDC+, UDC-) of the DC intermediate circuit (10) in such a manner that a resulting total power dissipation in said one or more groups of said at least one group of at least two controllable power semiconductor switches of the converter causes a voltage of the DC intermediate circuit to decrease below a predetermined voltage level within a predetermined time.
