The Detection of Voltage Extreme Points of the Shielded Power Supply Bus under the Ultrashort Pulse Excitation

Abstract

The paper investigates the propagation of the ultrashort pulse along the conductors of the power supply (PS) bus with improved design. The common-mode and differential-mode excitations of the 100 V ultrashort pulse were used. Eight propagation ways were considered. The voltage maximum of 13.569 V was obtained with a common-mode excitation, and the voltage minimum (minus 16.683 V) was obtained with differential-mode excitation for 50 Ohm terminations.
