Complete Space Vector Modulation (SVM) algorithm is developed for a three-phase, three-level converter. Special attention is given to minimization of output ripple and voltage balance of the dc-link input capacitors. Verification of the proposed SVM algorithm is done by computer simulation. Comprehensive small-signal modeling of the three-level converter with a resistive load is developed the first time. Steady-state solutions reveal that the voltage across dc-link input capacitors is constant at the half of the dc-link voltage.viii, 92 leavesBTDapplication/pdfenIn Copyrightthree-level converterLD5655.V855 1997.C673Thesishttp://scholar.lib.vt.edu/theses/available/etd-08222008-063802/
