Abstract
A method and arrangement for phase-fired control is provided, in which all controllable electric switching elements are linked by a common controller that has a first input for a first control signal. A set point value is pre-defined as a first input variable and assigned to a device for controlling the controllable electric switching elements. Current flowing through each switching element is measured and transmitted to the device for controlling the switching elements as a respective second input variable. The current value of the voltage in the load is measured and transmitted to the device for controlling the switching elements as a third input variable. The device for controlling the switching elements controls all switching elements in a targeted manner by use of the first, second and third input variables. A maximum of two switching elements are active at any one time.
