The paper aims to develop a CAD tool power electronics converters.
Integration of knowledge base techniques with OOP paradigm. Using Visual Basis class builder, 15 classes were built to form the kernel of the tool's KB.
A knowledge‐based CAD tool was developed to ease the design of power electronics converters. It can be considered a learning aid tool too.
The knowledge base of developed tool can be expanded to accommodate large number of topologies. The GUI can be also ameliorated to a better look and interaction process.
With proper enhancements, the purpose of the developed tool can be upgraded from educational one to industrial one.
Beside the methodology, the new thing in the paper is the specificity of the application of the tool (i.e. in power electronics).
