FIELD: electricity.
SUBSTANCE: from a flow of a power system power, an inductive current component of one or more fixed frequencies is extracted by means of a bridge PWM rectifier of transistor type, as an equivalent energy of sequence of unipolar periodically repeating width-modulated pulses of current, duration of which changes according to the law of variation of envelope of inductive component of current extracted from the power system.
EFFECT: improved efficiency and expansion of functional capabilities.
