Abstract:
Disclosed herein is a device for reducing noise generated by an electrical component, the device including a stiffening component secured to an electrical component, wherein the stiffening component provides rigidity to the electrical component, thereby reducing the mechanical resonance of the electrical component during operation. The electrical component has at least one end face and a flange portion that includes a flange face that extends about a perimeter of the end face. The flange face is substantially parallel to the end face, wherein the stiffening component is secured to the flange face of the electrical component such that it does not extend into a plane of the end face. Further, the stiffening component can include a stiffening portion and a securing portion, wherein the stiffening portion is secured to the flange face of the electrical component by the securing portion. Further, the electrical component can be a power semiconductor device.
