Controlling at least two inverters with common intermediate circuit involves exchanging control and/or information signals between inverters via intermediate circuit rail system for inverters

摘要

The method involves exchanging control and/or information signals between the inverters (12) via an intermediate circuit rail system (14) for the inverters. The control and/or information signals are modulated onto high frequency carrier signals that are coupled into the intermediate circuit rail system or coupled out of the intermediate circuit rail system. The control and/or information signals are binary coded. AN Independent claim is also included for the following: (a) a converter arrangement with at least two inverters with a common intermediate circuit.
