Abstract

Powers of power generators differ by a factor of two, and they are combined in accordance with a binary number depending on an input signal. The controller has a reversible binary counter (3) whose outputs (A1-An) each allocated to a binary place, control the power generators (H1-Hn). A control circuit (14, 15) delivers to the counter counting pulses so long as the input signal (Vi) differs from a reference signal (Vr) outside a dead zone. The system enables alteration of output power over a wide range proceeding in comparatively small steps.
