This paper introduces the Modified conventional SVM (MSVM) in order to improve CMV, switching losses, and THD feature of two-level Voltage Source Inverter (VSI). The proposed method divides nulltime, resulted from SVM, to these of two nearby active vectors, forming sector, to calculate new duty cycles. This modification also can be envisaged as transferring matrix, in which its elements are function of percentage of allocating null-time to active ones. Avoiding null-vectors not only result in reduction of CMV peak value but also lead to mitigating THD. Moreover, MSVM mitigates the number of commutations which are proportional to switching losses. In this work, theoretical approach to calculate switching losses, respecting load power factor is formulized. Mathematical approaches, simulation results, carried out through MATLAB/Simulink environment, and finally experimental results verify its validity in above-mentioned achievement. Proposed strategy is simply applied without adding any extra hardware and complex calculations.
