Abstract
Nowadays, three-phase ac-ac matrix converters are becoming popular for various applications. They are classified as direct and indirect matrix converters. The ultra-sparse matrix converter (USMC) is one such simplified configuration of matrix converters. Compared to both conventional direct matrix converter (DMC) and indirect matrix converter (IMC), the USMC has reduced switch count. However, the main drawbacks of USMC are higher dc-link voltage ripple and lower voltage gain. This paper focuses on increasing the voltage gain, reducing dc-link voltage ripple and minimizing the number of energy storage elements of USMC. Hence, a hybrid switched inductor step-up ultra-sparse matrix converter is proposed for a wind generator. Simulations results are carried-out on the proposed converter and the results are presented. In addition, a cost comparison of the proposed converter and conventional matrix converter topologies is presented.
