Abstract
The standard IEC 61000-3-2 specifies harmonic emission limits for equipment with input currents below or equal to 16 A. The limits, as well as the related test procedures, have been developed several decades ago and are specifically dedicated to older types (“classical”) equipment with line-commutated circuit topologies. Nowadays, the share of “modern” power electronic (PE) equipment with self-commutating topologies is continuously increasing and the suitability of the limits, methodologies and test procedures in IEC 61000-3-2 should be critically reviewed. This paper compares the harmonic performance of around 100 “classical” and 50 “modern” PE household appliances, which can be generally denoted as “mass-market equipment”. Based on the identified differences, the paper discusses needs and initial approaches for updating of existing limits and test procedures. The paper aims to raise awareness to the qualitatively different behaviour of classical and modern PE equipment and contribute to the development of appropriate standards, which should ensure appropriate EMC levels in existing LV networks and future grids.
