Temperature is one of the most important factors that affect the performance of power electronics systems. It is important that thermal management is considered initially at the design stage of the systems. Because of its advantages of being low cost, high accuracy, and adaptable, computer simulation based analysis and design techniques have become important tools for power electronics designers....
Light emitting diodes (LEDs) can provide a number of benefits such as adaptive light control, reduced form factor and other novel techniques to ultimately improve the performance of the display. Some of the design challenges in adopting LEDs are to fully understand their effect on the thermal management, reliability, optical and viewability performance of the display. For the display designer this...
Power electronic modules (PEMs) are widely used in aerospace and automotive applications where high reliability is essential. Solder joint fatigue is one of the major failure mechanisms in PEMs, a reliability assessment method for this failure mechanism is presented in this paper. Differing from the traditional reliability prediction methods, this approach allows the reliability performance of PEMs...
This paper discloses the design optimization of embedded electromagnetic bandgap (EBG) structures for noise suppression in power/ground plane applications. We have established the design rules for EBG using finite-element based parametric analysis and extraction of the equivalent circuit models for EBG. The concept can be applied to achieve desired operating frequencies and dimensions, by tuning values...
