The study and realization of three-level SVPWM algorithm for high power inverter

摘要

A novel simplified space-vector pulse width modulation (SVPWM) algorithm for high power three-level inverter is analyzed in this paper. The space-vector module algorithm of two-level inverter is applied to that of three-level inverter using DSP and FPGA. A 22Kw and a 1000kW three phase asynchronous motor are taken as experimental subject in lab and field respectively. The experiment results show the effectiveness of the novel SVPWM algorithm, and can reach good performance in practice.
