POWER MODULE LAYOUT FOR AUTOMOTIVE POWER CONVERTERS
First Claim
1. An automotive power converter comprising:
- a substrate;
first and second electronic devices on the substrate;
at least one conductive member coupled to the substrate and having a first device portion electrically coupled to the first electronic device and a second device portion electrically coupled to the second electronic device; and
first and second terminals electrically coupled to the at least one conductive member such that when a power supply is coupled to the first and second terminals, current flows from the first terminal to the first device portion substantially in a first direction and from the second terminal to the second device portion substantially in a second direction,wherein the first direction has a first component and the second direction has a second component opposing the first component.

Abstract
An automotive power converter is provided. The automotive power converter includes a substrate, first and second electronic devices on the substrate, at least one conductive member coupled to the substrate and having a first device portion electrically coupled to the first electronic device and a second device portion electrically coupled to the second electronic device, and first and second terminals electrically coupled to the at least one conductive member. When a power supply is coupled to the first and second terminals, current flows from the first terminal to the first device portion substantially in a first direction and from the second terminal to the second device portion substantially in a second direction. The first direction has a first component and the second direction has a second component opposing the first component.
