DESIGN AND ANALYSIS OF THREE-PHASE SPLIT SOURCE INVERTER

In many DC-AC power conversions a voltage source inverter (VSI) along with an additional DC-DC boosting stage is required. To overcome this problem in VSI, a split source inverter is preferred. This paper presents a combination of boost stage and VSI stage as a single unit DC-AC power conversion named as split source inverter (SSI). The proposed topology require three additional diodes with same number of active switches of VSI and eight same states of conventional pulse width modulation. This work present the analysis of SSI with sinusoidal pulse width modulation technique. The developed SSI model is simulated on MATLAB/SIMULINK environment. Simulation results have been obtained for inverter voltage, inductor current, output line current and total harmonic distortion of output line current.
