Thermal network calculation model for phase change material with SPICE circuit simulator

Microencapsulation of Butyl Stearate as Phase Change Material by Melamine Formaldehyde Shell for Thermal Energy Storage

Butyl stearate as a phase change material was microencapsulated within melamine-formaldehyde resin using emulsion polymerization. Morphology and thermal specification of produced microcapsules were studied by Fourier transform infrared spectroscopy, FT-IR, scanning electron microscopy, SEM, and Differential scanning calorimetry analysis, DSC. FT-IR spectra validated the existence of the butyl s...

Thermal Analysis of Thermal Energy Storage Systemwith Phase Change Material

Due to fast depletion of conventional energy sources and ever increasing demand of energy, many researchers started paying attention to renewable energy sources.Thermal Energy Storage (TES) is one of the key technologies for energy conservation and has recently been developed to a point where it can have a significant impact on modern technologies. The present work deals with the study of a sph...

Spice Compatible Circuit Model for Reluctance K

We are the rst to develop SPICE compatible circuit model for reluctance K It can be combined with any reluctance based extraction method to perform RLC simulation directly without the need of inverting reluctance matrix back into inductance domain or modifying conventional simulator To build symmetrical reluctance matrix we also proposed blocked K method based on group concept to cover more mag...

A robust electro-thermal IGBT SPICE model: Application to short-circuit protection circuit design

Integrated Circuit Performance Optimization with Simulated Annealing Algorithm and Spice-pac Circuit Simulator

The circuit design problem consists in determining acceptable parameter values (resistors, capacitors, transistor geometries . . . I which allow the circuit to meet various user given operational criteria (DC consumption, AC bandwidth, transient rise times, etc). This task is equivalent to a multidimensional and/or multi objective optimization problem: n-variables functions have to be minimized...
