Abstract (en)
[origin: EP0442139A2] In order to improve the graduation of the power output by electrical loads, the invention provides a method and a device for controlling the power of at least one load with a combination of a balanced multi-cycle control, especially at one-third clock rate with interval times which are less than the times within which processes in the same sense are regarded as a change, with switching-off times which are longer than switching times that result in flickering.
