A test arrangement for testing a power electronics controller, wherein the controller has supply connections and load connections. A plurality of power electronics modules each have supply connections, at least one load connection, and an interface for controlling the power electronics module. In an operational state of the test arrangement, the supply connections of the controller are each connected to the load connection of a supply-side power electronics module and the load connections of the controller are each connected to the load connection of a load-side power electronics module. Thus, a rapid supply-side current regulation can be realized in a simple way in that the control device calculates at least the determined actual currents at the load connections of the supply-side power electronics modules from determined electrical connection variables of the load connections of the load-side power electronics modules for use for the feedforward control.

Test arrangement for testing a power electronics controller

A test arrangement for testing a power electronics controller. An intermediate network current in the electrical intermediate network is reduced in that the intermediate network current flowing in the intermediate network is determined by the controller and the controller changes at least one control value of at least one of the load-side power electronics modules in such a way that the intermediate network current is reduced when the interface of the load-side power electronics module is applied with the modified control value.

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.
