<p>An EMI filter (70, 170) for use with a blower (16, 116) having a conductive case (34) at blower ground potential isolated from chassis ground potential is disclosed. The blower (16, 116) is powered by two supply lines (56, 58, 156, 158) which are capacitively coupled by a first capacitor (72, 172) and a second capacitor (78, 178) to blower ground (54). A third capacitor (184), or a capacitor in a motor controller (47) contained within the Faraday cage of the case (34), capacitively couples supply lines (56, 58, 156, 158).</p> |
