This paper presents a comparative evaluation of three phase Voltage Back to Back Converter (VBBC) and three phase Matrix Converter (MC)fed Induction Motor (IM) drive. These two topologies are developed using Space Vector Modulation (SVM) technique and simulated in MATLAB/SIMULINK. Both the topologies are functionally equivalent in terms of input power quality and energy regeneration capabilities but need to be compared in terms of performance as well as complexity due to the high number of switches involved in these two converters. In particular, the Total Harmonic Distortions (THD) of the two converters are compared. Although The Matrix Converter has a higher number of semiconductor switches, the absence of energy storage elements reduces the size of the circuit topology.
