High current PCBs - system integration of busbars and electronics

Abstract

This paper presents a technique to combine high currents and microelectronic control in a single system for power train and power supply applications. The combination is achieved by incorporation of busbars and other massive copper bars into a printed circuit board (PCB) to obtain high current load capability as well as heat sink for components with considerable power dissipation. Typical applications of automotive industry or avionics handle currents in the order of up to 1000 Ampere.
