My research interests include optimized design of transformers and rotating electrical machines, finite element field calculations and circuit analysis. I have developed computer programs for PCs in all these areas. The first three (IEEE CAP) publications below give an overview of the programs.

PC-Programs
Most early versions of the programs were made for MS-DOS before Windows became the dominant operating system, some of them even before the age of personal computers. They are now being run under Command Prompt, which is found in Windows Accessories. Commands are typed on the keyboard and executed by striking Enter. Recent changes in Windows have made it necessary to reprogram the graphics with Visual Basic 2008. Compatibility between different versions of Windows has also become a problem, but the programs now work on my two computers with:
Windows Vista Home Premium, Intel Core 2 Duo CPU P8400
Windows XP Home Edition, Intel CPU T2300
FLD6 - Laplacian Electrostatic Fields
FLD7 - Complex Potential Electric Fields
FLD8 - Skin Effect and Eddy Currents
FLD10 - Reactors with Series Connected Layers
FLD11 - Poissonian Magnetic Fields
FLD12 - Complex Potential Transformer Leakage Flux
FLD13 - Synchronous Machine Field Program
FLD14 - Parallel Layer Air Core Reactors
FLD15 - Rectangular Core Transformer Leakage Flux
FLD16 - Induction Motor Field Program
PECAN - Power Electronic Circuit Analysis
ACCAN - Ac Circuit Analysis
HARM - Spatial Harmonic Magnetomotive Forces
SYNOP-SYNAN - Synchronous Generator Optimization and Analysis
INDOP-INDAN - Induction Motor Optimization and Analysis
TRA1 - Power Transformer Design
TRA2 - Small Transformer Optimization
Demo Programs
A zip-file should be downloaded into an empty directory. Double-clicking will extract the files. The demo will be run under Command Prompt. To get instructions, double-click on MESSAGE.
FLD12.ZIP
The demo allows the user to analyze his own transformer, but it is restricted to two layers (windings). The full version can have up to 30.
TRA2.ZIP
The entire program with source code and everything is in the demo.
ACCAN.ZIP
The demo can do everything the full version can, except that it is limited to 50 variables (node voltages + branch currents) and 5 mutual reactances.
