This paper discusses a control scheme of Indirect Matrix Converter which includes space vector modulation to stabilize the frequency variations. The terminal voltage and frequency of any synchronous machine can be controlled easily with this scheme. The proposed method leads to reduction of harmonics and losses predominantly increasing the efficiency of output. More over the control strategy is also very much flexible in their operation at any rated power. This work is mainly focused on the Matlab/Simulink implementation of SVM technique with Zero current switching for IMC. The novelty of this work is that a detailed analysis of directly AC to AC conversion with no energy storage element has been done and the SVM technique for IMC is implemented in Matlab/Simulink embedded system. The techniqe has been successfully implemented in wind energy conversion system and results have been analyzed.
