An investigation of component interaction and analysis of its impact on electro-thermal behaviour in a power dense boost converter topology

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. Results show that use of the thermal model parameters that are derived from Finite Element Analysis method can predict the temperature accurately and can also take into account of the thermal interaction between components, an issue that has not been fully investigated in this area of research.
