FIELD: electric engineering. SUBSTANCE: device has power supply and oscillating circuit which is connected to power supply through thyristor gate. Oscillation circuit has induct and capacitor battery. Corresponding method involves pulse-phase control of thyristor gate using conversion of sine source current into pulses and its supply to oscillation circuit with given coefficient K of power supply frequency division. System of pulse-phase control has divider of frequency of current pulses. EFFECT: increased functional capabilities. 4 cl, 4 dwg
