    Abstract: A method for controlling a plurality of power converters connected to a power supply network is described. Each power converter comprises high-power semiconductor devices. Control signals are sent between a controller and a wireless node of one or more of said plurality of power converters using a wireless communication system. The control signals are transmitted to a local wireless node of one or more of a plurality of power converters. The data transmissions include data packets comprising control information such that a clock of the local wireless node can be synchronized using time synchronization information of the wireless communication system. In other aspects of the invention a system employing the method and a computer program for carrying out the method are described.

    Abstract: A system for a machine, in particular an automated production machine, has a large number of proximity sensors. Each proximity sensor has at least one secondary winding that is suitable for drawing power from a medium-frequency magnetic field. At least one primary winding, which is fed from a medium-frequency oscillator, is provided for supplying the proximity sensors with electrical power without using wires. Each proximity sensor is equipped with a transmitting device that emits radio signals, which contain sensor information of interest, to a central receiving device that is connected to a process computer for the machine. A proximity sensor and a primary winding for this purpose are also proposed.
