IEC 63497:2026, which is a product standard, is intended to specify the EMC, performance and safety requirements of shunt-connected active correction devices (ACD) with rated system voltages not exceeding 1 000 V AC or 1 500 V DC.
These devices can be either cord or permanently connected. They can be movable, stationary, or fixed devices.
An ACD includes both a static VAR generator (SVG) and an active harmonic filter (AHF).
The primary function of a shunt connected ACD is to do one or more of the following:
- active harmonic filtering;
- reactive power compensation;
- unbalanced load compensation.
Additional functions of a shunt-connected ACD, not addressed by this document, can be the following:
- flicker compensation;
- interharmonic component filtering.
In case of hybrid devices, combining a passive harmonic filter and an ACD, this document covers only the active part.
This document does not cover
- active mitigation functions part of another device (variable speed drive, uninterruptible power supply, dynamic voltage restorer, etc.),
- switched power capacitors,
- switched inductors,
- passive harmonic filters,
- energy storage converters, and
- series-connected active correction devices.
