Common-Mode Radiated Emission Analysis of Cable-Connected Printed Boards with Adjacent Metal Chassis by Imbalance Difference Model

The common-mode antenna (CMA) model and the equivalent differential-mode (DM) circuit are based on imbalance difference theory. theory describes mode conversion between common (CM) differential by focusing difference. CMA has been proven to provide excellent estimations of CM radiated emission. In this work, is combined with DM extend practical applications that include in both directions radiation loss. applied cable-connected printed boards (PCBs) an adjacent metal chassis imitates a signal transmission system placed close chassis. calculated emission using field-and-circuit co-simulator, considering Simulation results confirmed precisely estimated being separated from also provided physical insights into EMC design will enable be efficiently reduced.
