<strong>EMC</strong> (compatibility)<br />
St<strong>and</strong>ards compliancy<br />
Switching harmonics / THD<br />
(up to 25 th / 40 th harmonic)<br />
Conducted emissions<br />
(150 kHz – 30 MHz)<br />
Radiated emissions<br />
(30 MHz – 1 GHz)<br />
EMI (interferences)<br />
Malfunction through self disturbance<br />
Performance de-rating<br />
…through load imbalance<br />
…through voltage/currents overshoots<br />
