The invention relates to a simple, cost-effective construction that guarantees a reliable operation of at least one carrier for receiving at least one power module comprising a power component. According to the invention a hybrid circuit is arranged on at least one of the carriers as a thick-film circuit, which has at least one thick-film resistor as a discharge resistor for discharging the energy of at least one component that is provided as an energy store. The power module can be used as a power converter for electric motors.
