1. A test arrangement for testing a power electronics controller, the controller comprising:
supply connections for power supply and load connections for controlling an electrical load; and
at least two power electronics modules that each have a supply connection for power supply, at least one load connection to provide at least one electrical connection size, and an interface to control the power electronics module,
wherein, in an operational state of the test arrangement the supply connections of the controller are each connected to the load connection of a power electronics module on the supply side for the provision of an electrical connection size at the supply connections of the controller,
wherein, in the operational state of the test arrangement, the load connections of the controller are each connected to the load connection of a load-side power electronics module for the provision of an electrical connection size at the load connections of the controller, the supply connections of the supply-side power electronics modules and the supply connections of the load-side power electronics modules being connected to each other via an intermediate electrical network, and the interfaces of the supply-side and the load-side power electronics modules being applied with control values by at least one controller for setting electrical connection sizes at the load connections of the power electronics modules,
wherein an intermediate network current flowing in the intermediate network is determined by the controller, and
wherein the controller changes at least one control value of at least one of the load-side power electronics modules such that when the interface of the load-side power electronics module is applied with the modified control value, the intermediate network current is reduced.
