Abstract:
1. An apparatus for converting electrical energy to heat in a field of drive and/or high-voltage technology, the apparatus comprising: a plurality of bipolar submodules connected in series forming a submodule series circuit, each of said bipolar submodules having first and second connecting terminals being switchable into a series connection, said bipolar submodules having a braking resistance formed of individual braking resistances, and at least some of said bipolar submodules having an energy store connected in parallel with a respective one of said individual braking resistances, said bipolar submodules each having a controllable braking power semiconductor for controlling a conversion and which, in a braking position, allows a current to flow via said respective individual braking resistance and, in a normal operating position, interrupts the current flow via said respective individual braking resistance, said individual braking resistances and said energy store connected between said first and second connecting terminals.
