Electromagnetic Characteristics of a High Density Motor Drive System Using a Printed Power Circuit Board

概要

論文の詳細を見る
This paper describes a high-density motor drive system in which the power transmission lines are formed by a multi-layer printed board, making it possible to reduce inductance of lines. The structure of the power transmission lines between the converter and the inverter is determined, based on calculations of the magnetic field distribution generated by the differential (normal) mode current, which leads to an increase in radiated emissions due to the common mode current. The printed power circuit is experimentally verified as an effective way to reduce the electric field intensity from the radiation.
