Abstract
An apparatus, such as a power converter, includes first, second and third core bus plates arranged in parallel. The apparatus also includes a first bus extension plate joined to the first core bus plate and extending therefrom at a first angle and a second bus extension plate joined to the second core bus plate and extending therefrom at a second angle. The apparatus further includes a third bus extension plated joined with the third core bus plate and disposed parallel to the first bus extension plate and a fourth bus extension plate joined with the third core bus plate and disposed parallel to the second bus extension plate.
Claims2
