Abstract
The invention relates to a pulse resistor for a frequency converter in the higher voltage and capacity range. The inventive pulse resistor is characterized by comprising at least two bipolar subsystems () and a resistor element (), said subsystems () and said resistor element () being connected in series. The inventive pulse resistor is devoid of the drawbacks of known pulse resistors, it can be finely controlled by a brake current (iB) and can be adapted to any medium voltage by simple means.
