A neutral point clamped three-level inverter is used to explain the scheme. We briefly analyze working principle and algorithm of SVPWM, proposing a simple building method of sector judge-ment model based on Matlab. Through the observation and analysis of the simulation waveform, the cor-rectness of the algorithm is verified, also providing the basis for debugging and studying the actual hard-ware circuit.
