A laminated bus bar for a low inductance has been used recently in power electronics circuits. While higher speed switching has been required, an electromagnetic induced noise due to the magnetic field of the pulse current occurs in power circuits. In this research, the induced noise is verified from the relationship between the noise current and the impedance of laminated bus bars due to the difference in the power circuit structure. Furthermore, the induced noise related to the power circuit structure and normal/common mode currents in the circuit operation is discussed from experiments and equivalent circuits simulations.
