Electromagnetic interference (EMI)-proof electric device e.g. direct current (DC) voltage converter for high voltage transmission system of electric vehicle, has dielectric arranged between side faces of outer and inner conductors

摘要

The EMI-proof electric device (10) has an outer conductor (11) and an inner conductor (12) that are coupled with contact terminals respectively. The noise suppression capacitors (13Y,16Y) having predetermined capacitance, are connected with respect to inner and outer conductors respectively. A dielectric (14) is arranged between the flattened side faces of the outer conductor and inner conductor.
