Electromagnetic compatibility (EMC) tests

It seems there may be issues with guaranteeing this standard because when the TRIAC is
opened at 90°, the results are above their limits (the third and fifth harmonics failed, see
Figure
harmonic should be compared with the applicable limits. Taken exactly from the standard
description in the EN61000-3-2 standard,
The arithmetic average for the three cases (minimum, 90°, and maximum) for third harmonic
is 2.13 A (the average of 1.2 A, 3.4 A, and 1.8 A, respectively) and for the fifth harmonic is
0.7 A (the average of 0.7 A, 1.2 A, and 0.2 A, respectively). Since the limits for the third
harmonic is 2.3 A and the fifth harmonic is 1.15 A (see
under these limitations, proving that this type of EMI filter (with only the input capacitor
C7 = 470 nF) is suitable for AC motor speed control.

“The arithmetic average of the individual harmonic currents observed during the three
operating modes is computed for each harmonic order. This arithmetic average is
compared against the applicable limits”.
