Abstract

This paper describes how the physical layout and routing of power electronic circuits affects circuit performance, and influences EMI/RFI generation. Three categories of common circuit board layout effects are presented: impedance effects, capacitively induced effects, and inductively coupled effects. Guidelines are presented to determine the bandwidth of the signals of interest, along with methods for determining appropriate conductor geometries. Capacitor selection for decoupling, bypassing, and snubbing is also discussed
