A PC-based computer program for teaching the design and analysis of dry-type transformers

The authors illustrate the use of a new PC-based interactive computer program that has been developed specifically for the design of dry-type transformers. The BASIC language executes on a DOS-based PC with 512 kbyte of RAM and a CGA display. No additional software is needed. Simulation of a design case requires approximately 10 s of execution time on a 4.7 MHz PC/XT. The program enables transformer designers to test, modify, and optimize their designs. Once a base design is established, sensitivity to operating conditions can be easily determined by changing the appropriate input data and re-executing the program. This program can be a useful training tool in the classroom and an effective production design tool in the power electronics industry
