Abstract (en)
[origin: EP1923986A2] The device has an alternating current (AC) power controller (220) that operates an electromagnetic drive of a switch gear, where the controller includes two anti-serially connected transistors e.g. MOSFET-transistors and a semiconductor component e.g. thyristor. A control unit e.g. microcontroller, controls the power controller with a time function (240), which is controlled during a power-on process and represents an exponential function. Counter coupling-resistors balance the transistors, where the control unit has a resistor capacitor-unit.
