FIELD: electrical engineering. SUBSTANCE: level of output quasi-constant (filtered) voltage of controlled pulse voltage converter is changed in the course of operation of device. Device is supplemented with circuit of formation of control signals which inputs are linked to outputs of current pickup and master unit of controlling signals and which outputs are connected to controlling inputs of pulse voltage converter and unit of power keys. EFFECT: reduced pulsations of speed of electric motor are obtained thanks to feeding of armature circuit with practically constant current changing by specified law. 3 dwg
