Abstract
A power module includes at least one carrier body for mounting at least one power component thereon, and at least one energy storage component. For this purpose, a hybrid circuit is arranged as a thick film circuit on at least one of the carrier bodies, and the hybrid circuit includes at least one thick film resistor as a discharging resistor for discharging the at least one energy storage component. The power module is adapted for use as a power converter for electric motors.
