Transient thermal network model identification for power module packages

transient analysis in power network

a simple method is described for analysis of transients in power network. the method is developed for analysis of transformer and generator winding resonances due to their interaction with transmission lines caused by switching surges. the method is already used for calculation of overvoltages which had resulted in damages in the transformer winding of a hydro power plant. nonlinearity in the i...

Three Dimensional Transient Numerical Modeling of Temperature Distribution and Output Power in Photovoltaic Module

According to the effect of temperature on the output power of a photovoltaic module, this research tries to calculate the temperature distribution in a photovoltaic module by numerical solving of the energy balance equations. Therefore, its output power can be accurately predicted. For this purpose, several photovoltaic modules are modeled in detail in the COMSOL software. A new method for calc...

Module Network Model for Ontology Merging

Ontologies are an important feature of Semantic Web. The massive information created by the exponential growth of webpages requires sharing of ontologies. One of the key features to improve Semantic Web is to develop ontologies. Manual annotations of the webpages require massive amounts of resources. A feasible solution to reduce cost is to build ontologies, merge ontologies and enrich ontologi...

Improved thermal management for GaN power electronics: Silver diamond composite packages

A novel packaging solution for GaN power electronics for efficient heat extraction in high power devices is presented. The benefits of using silver diamond composites as base plate in packages for GaN power bars are demonstrated. Micro-Raman thermography measurements were carried out to probe the device temperature for devices mounted on different base plates, silver diamond composites and stan...
