Steve Butler explains how switching power supplies generate conducted emissions and demonstrates how VPT’s EMI filters help DC-DC converters meet MIL STD 461 limits. The video compares Revision C and Revisions D/E/F test setups, shows how LISNs and feed through capacitors are used for CE measurements, and walks through lab results confirming compliance when proper filtering and layout practices are applied.
