FIELD: electricity.SUBSTANCE: method to control three-phase sinusoidal voltage is based on alternation of connection of an excitation winding of a voltage booster or to a source of three-phase voltage or to a three-phase resistor. Switching is carried out by a three-phase semiconductor switch. At the same time the oscillating circuit, being formed by a serial winding of the voltage booster and the capacitor, is used to generate anti-distortions of current, and summing them with the current of the primary winding of the voltage booster, they provide a sinusoidal current of the network, sinusoidal voltage of the load.EFFECT: reduced losses in loads in one or several power transformers and in a power transmission line and use of loss energy for production needs.5 dwg |
