Abstract Three-level inverter has many advantages, such as low switching frequency, low harmonics, low multiples of the carrier frequency and the carrier frequency of the harmonic content comparing with the two-level inverter. But the three-level inverter voltage space vector pulse width modulation (SVPWM) algorithm is complex and large amount of computation controller. To solve the above problem, this paper proposes an improved three-level SVPWM algorithm. The algorithm with simple logic to determine the vector can be obtained by reference the specific location of the nearest three vectors and synthetic reference vector, greatly simplifying the distribution of the reference voltage vector synthesis and function of time. Finally, a three-phase permanent magnet synchronous motor is controlled objects using Matlab/Simulink validated, indicate the feasibility and validity of the method.
