Design of sparse matrix converter

Abstract

The aim of this project is to design and implement the Sparse Matrix Converter. The Sparse Matrix Converter consist of 15 Transistors, 18 Diodes, and 7 Isolated Driver Potentials. Compared to the direct matrix converter this type provides identical functionality, but with a reduced number of power switches and an improved zero DClink current commutation scheme. It provides lower control complexity and higher safety and reliability. In the matrix converter, modulation and control techniques are so far the principal topic of research and development as the practical experience is still very limited
