Open publisher page 0 citations

Abstract

Based on SVPWM for the two-level inverter,the basic principle of space vector pulse width modulation(SVPWM) for three-level inverter is analyzed.The three-level inverter complex calculations of the NTV principle can be avoided when following the sector sub area techniques used in two-level.The process is concise and perspicuous to make the three-level controlled system be realized easily.At last,the simulated result is given,which confirmed the validity of SVPWM algorithm brought forward.
