Description
Summary:EMI suppression and filtering are becoming increasingly important as the use of small DC motors proliferates. In an effort to develop a compact filter whose performance surpasses that of traditional filters, a production version of a small automotive windshield-washer DC-motor assembly as a DUT in an EMI measurement set up. Our test setup included a broadband GTEM cell for our radiated emissions measurements. The GTEM-based test setup prove to be an effective method for quickly comparing the EMI performance of the single-component filter with traditional multicomponent filter configurations.
