Electro-Thermal Simulation of Vishay Siliconix Power MOSFETs on a P-Spice Platform
More InfoLess Info
Separate R-C thermal and P-SPICE circuit models are provided on the product information page for each power MOSFET on the Vishay web site. Previously, designers had to perform separate simulations for electrical and thermal circuits, but now Vishay Siliconix provides a combined electro-thermal model for total simulation. This application note will illustrate the validity of the combined model. We will use multiple simulation runs using electro-thermal model files to demonstrate that the results are comparable with the simulation results using standard P-SPICE library files.
