In this paper it is shown how Finite Element Analysis can be exploited for the calibration of detailed compact thermal models of the components in the power converter topology. Parameters extracted from Finite Element transient thermal response are used to build the thermal network in conjunction with an electrical model of the converter for the prediction ofpower losses in the components.

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...
This paper discusses the modelling tools used to predict the performance of a liquid crystal display using an array of light emitting diodes (LEDs) as the backlight. 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...
In order to meet the through-life reliability targets for power modules, it is critical to understand the response of typical wear-out mechanisms, for example wire-bond lifting and solder degradation, to in-service environmental and load-induced thermal cycling. Application of accurate wear-out models can identify the dominant failure mechanisms at the design stage and can be employed in reliability...
Health management and reliability form a fundamental part of the design and development cycle of electronic products. In this paper compact real-time thermal models are used to predict temperatures of inaccessible locations within the power module. These models are then combined with physics of failure based reliability analysis to provide in-service predictions of crack propagation in solder layers...
