Abstract
A device converts electrical energy into heat in the field of drive voltage technology and/or high voltage technology. The device contains a brake resistance and at least one controllable brake power semiconductor for controlling the conversion, enabling a rapid and economical transformation of effective power into heat as required. To this end, the brake resistance contains a plurality of individual brake resistances that are each part of a bipolar submodule. The submodules are connected in series, form a submodule series connection, and at least partially contain an energy accumulator respectively connected in parallel to an associated individual brake resistance and a controllable brake power semiconductor, which allows the current flow over the respectively associated individual brake resistance in a brake position, and interrupts the current flow over the brake resistance in a normal operating position.
