    Abstract: The present invention concerns a method and system for detection of a circuit board to be installed in an apparatus such as an electric drive. At least one first element is fixedly arranged at at least one defined position on the surface of the circuit board and at least one second element is fixedly arranged at at least one defined position in a housing of the circuit board. The at least one first element interacts with the at least one second element during installation of the required circuit board. A matching signal or decoding signal is generated when the first element and the second element interact. The invention further concerns an apparatus such as an electric drive with at least one circuit board arranged in a housing.

    Abstract: An exemplary method and arrangement for balancing currents of power semiconductors. The arrangement including multiple power semiconductor units and a central control unit. Each power semiconductor unit includes a power semiconductor and the central control unit and the power semiconductor units are arranged in a bi-directional ring, in which the central control unit sends control information for the power semiconductor units in both directions in the bi-directional ring and each power semiconductor unit receives the control information in both directions and forwards the received control information. Each power semiconductor unit configured to receive the control information from the first direction at a first time instant, receive the control information from the second direction at a second time instant, calculate a midpoint between the first and the second time instants, and control the power semiconductor component according to the control information after a time delay after the calculated midpoint has elapsed.
