Patent number: 6528903Abstract: A converter system has a number of individual converter modules, which are in the form of load converter modules or power supply system converter modules and are connected to one another via a DC voltage intermediate circuit which has two DC voltage busbars and a DC voltage intermediate circuit capacitance arranged between the DC voltage busbars. A defective converter module is isolated from a common intermediate circuit, in which interruption-free further operation of the other modules on the intermediate circuit is possible and in which the isolating means are not destroyed. The DC voltage intermediate circuit capacitance is subdivided into a number of parts corresponding to the number of converter modules.
