Abstract

An electrical circuit for a power converter is described. The circuit has been provided with several semiconductor switches and capacitors used for operating the power converter. A brake resistance for lowering energy is provided and is connected to the semiconductor switches provided without the need for an additional switch. The operation of the power converter and the current flowing through the brake resistance can be controlled by means of the existing semiconductor switches.
