Title:
HIGH HARMONIC SUPPRESSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/270470
Kind Code:
A1
Abstract:
This high harmonic suppression device comprises: a power converter that is connected to a system line between an AC system and a load, and that generates AC voltage and outputs the result to the system line; and a control means that detects a high harmonic component of load current flowing in the system line, determines a target value for compensating current to be added to the load current in order to suppress the high harmonic component, multiplies the target value by a gain based on the impedance between the system line and the power converter, thereby determines the compensating voltage required to supply compensating voltage corresponding to the target value to the system line, and causes the compensating voltage to be generated and output by the power converter.
