FIELD: electricity.
SUBSTANCE: active device (40) for compensation of harmonic currents of the main current designed for parallel connection to the input circuit of a converter (28), comprising a sensor (44) of supply current, a current generator arranged as capable of current supply to the input of the converter (28) depending on the force of the harmonic current measured by the current sensor (44). The current generator is arranged as capable of generation of a current and its supply to the input of the converter (28), apart from the harmonic current, which k times exceeds the harmonic current measured by the current sensor (44), at the same time k is positive.
EFFECT: limitation of noise occurrence.
