Aiming at narrow pulse problem occurs in modulation of three-level inverter modulation algorithm
on the basis of analyzing normalized sector three-level space vector pulse width modulation( SVPWM) algorithm
generation causes and effects of narrow pulse of this modulation method are researched
a narrow pulse suppression algorithm based on normalized sector three-level SVPWM algorithm. The feasibility of the method is proved by theoretical deduction. This method can not only restrain occurrence of narrow pulses
but also realize compensation. Correctness of the algorithm is proved by the simulation results of MATLAB/SIMULINK.
