Abstract
The invention concerns a frequency converter for an electromotor with an intermediary circuit, in which a braking circuit with a switch and a load is arranged. With such a frequency converter, it is possible to ease the demands on protection measures, even though the load is placed outside the frequency converter. For this purpose the load is galvanically separated from the intermediary circuit.
