Analysis and simulation study of extended boost z-source sparse matrix converter

This paper presents a new topology of sparse matrix converter (SMC) based on extended boost z-source inverter topology. The proposed topology gives more boosting factor as compared to other z-source matrix converters with same modulation index. Space vector pulse width modulation (PWM) technique as well as zero current switching has been implemented for the proposed topology. Further detail analytical study of the proposed topology has been done. It can be concluded that, the proposed topology can be more suitable for motor drives, wind energy conversion systems (WECS), HVAC applications. Further boosting factor can be easily extended by cascading basic impedance networks. Also the variable frequency output voltage has been generated from the proposed topology with proper modulation techniques. The effectiveness of the proposed topology is verified with MATLAB/SIMULINK simulation study.
