Abstract

The paper deals with electromagnetic conducted emissions due to brushless direct current motors (BLDC) used in driving air handling units. According to the standards, these emissions have to be cancelled and the most straightforward method is to use passive EMI filters. In the main section the nonideal behavior of passive components use in EMI filters is presented along with their “hidden schematics” in the frequency range of interest.
