Abstract

A power electronics module for a test arrangement for testing a power electronics controller includes: supply connections for supplying energy; at least one load connection for providing at least one electrical connection variable; a supply circuit for providing electrical control voltages; a selection circuit with circuit breakers for switching one of the electrical control voltages onto the at least one load connection of the power electronics module; and an interface for controlling the circuit breakers. The supply connections of the power electronics module are AC supply connections. The supply circuit is a multi-phase circuit for providing a plurality of phase voltages on a plurality of phase conductors. The selection circuit connects a phase conductor to the at least one load connection of the power electronics module.
