Fleet Management Module Electromagnetic Interference Investigation
Keywords: Electromagnetic compatibility, precompliance testing, power supply filter
AbstractExperimental investigation of electromagnetic interference created by transport fleet management module is presented. Novel conducted interference evaluation technique has been rectified from CISPR 25 standard which was adapted to limited abilities for electromagnetic compatibility pre-compliance estimation. Several input filter topologies have been investigated aiming to evaluate the best performer. Common mode current measurement transformer has been designed and calibrated. Ferrite bead impedances have been measured in order to evaluate the suitability for DC input filtering. Common mode and differential mode conducted interference measurement results are given. Optimal filter selected.
