Abstract
Methods, systems, and apparatuses for a power card for use in a vehicle. The power card includes an N lead frame, a P lead frame, and an O lead frame each having a body portion and a terminal portion. The O lead frame is located between the N lead frame and the P lead frame. The power card includes a first power device located between the N lead frame and the O lead frame, with a first side coupled to the body portion of the N lead frame and a second side coupled to the body portion of the O lead frame. The power card includes a second power device located between the O lead frame and the P lead frame, with a first side coupled to the body portion of the O lead frame and a second side coupled to the body portion of the P lead frame.
Claims18
A power card for use in a vehicle, the power card comprising:
- an N lead frame having a body portion and a terminal portion, the terminal portion extending outward from the body portion, the body portion and the terminal portion being connected by a bend such that the body portion and the terminal portion lie on respective different planes;
- a P lead frame having a body portion and a terminal portion, the terminal portion extending outward from the body portion, the body portion and the terminal portion being connected by a bend such that the body portion and the terminal portion lie on respective different planes, a distance between the body portion of the P lead frame and the body portion of the N lead frame being greater than a distance between the terminal portion of the P lead frame and the terminal portion of the N lead frame;
- an O lead frame having a body portion and a terminal portion, the terminal portion extending outward from the body portion, the O lead frame being located between the N lead frame and the P lead frame;
- a first power device having a first side and a second side and being located between the N lead frame and the O lead frame, the first side coupled to the body portion of the N lead frame and the second side coupled to the body portion of the O lead frame;
- and
- a second power device having a first side and a second side and being located between the O lead frame and the P lead frame, the first side coupled to the body portion of the O lead frame and the second side coupled to the body portion of the P lead frame.
