Vehicle power module assemblies
First Claim
1. A vehicle power stage assembly comprising:
- a power stage housing including a first slot and a second slot;
a power stage supported by the housing; and
a pair of stacked DC leadframes of opposite polarity spaced apart from one another, each extending from the power stage through one of the first slot and the second slot, and each having distal and proximal ends,wherein the spacing between the leadframes is such that parasitic inductances associated with current flowing through each of the leadframes at least partially cancel one another.

Abstract
A vehicle power stage assembly is disclosed which may include a power stage housing, a power stage supported by the housing, and a pair of stacked DC leadframes. The pair of stacked DC leadframes are of opposite polarity and spaced apart from one another. Each of the DC leadframes may extend from the power stage and each has distal and proximal ends. The spacing between the leadframes may be such that parasitic inductances associated with current flowing through each of the leadframes at least partially cancel one another. Each of the leadframes may define a first and second side surface opposite one another. The first side surfaces may be coplanar and the second side surfaces may be coplanar. A distance between the spaced apart pair of DC leadframes may be based on a preselected amount of current and a material of the DC leadframes.

7. A vehicle power module assembly comprising:
-
a frame defining a stage cavity and a first slot open to the cavity; and a power stage disposed within the cavity and having a pair of DC leadframes extending through the first slot, wherein the first slot is defined such that distal and proximal ends of one of the leadframes are equally spaced apart relative to corresponding distal and proximal ends of the other of the leadframes. - View Dependent Claims (8, 9, 10, 11, 12)
