Abstract: A communication device can be used for communicating between a power equipment controller and power equipment devices of a high-voltage power electronics system. The communication device includes a controller interface communicatively coupled with the power equipment controller, an RF module coupled to the controller interface, and an antenna port coupled to the RF module. A mounting structure is configured to attach the communication device to a valve hall containing the power equipment devices. The mounting structure is permeable for RF signal communication between the communication device and power equipment devices in the valve hall. The mounting structure has a low voltage side to enable placement of the controller interface, the RF module and the antenna port so as to be shielded from disturbances due to high voltages inside the valve hall.

Abstract: A communications network for communication between at least one power electronics element and at least one control unit is disclosed. At least one transmit/receive unit of the communications network is configured to receive at least one signal from an upstream direction, and evaluate if the at least one signal is correctly received. In case the at least one signal is correctly received, the at least one transmit/receive unit is configured to forward, in an allocated first time slot, the at least one signal to a plurality of transmit/receive units in a downstream direction, and receive, in an allocated second time slot, a plurality of signals from the plurality of transmit/receive units as a response of the forwarded at least one signal.
