Three-level inverters has small harmonic component, torque ripple, high utilization rate of DC side voltage which is widely applied in active power filter system, middle, high voltage high power drive, flexible AC power supply system and becomes the research hotspot. Based on the diode clamped Three-level inverters regarded as the research object, the mathematical models of the voltage space vector modulation algorithm simulation and result analysis, simulation results show that the optimal voltage space vector modulation algorithm based on look up table is feasible, the design of FPGA three-level inverters system based on hardware circuit, taking the use of HDL, we designed the part of software, according to the design method of top-down design of space voltage vector signal generator IP core, finally the program is downloaded to the experimental development board in order to verify the IP core, the verification results show that the algorithm has real-time, high reliability, meet the real-time requirements of the system.

“…Jiang et al analyzed the reason of the oscillation of midpoint potential at low frequencies and deduced the function of oscillation; nevertheless, it does not provide the solution of the basic problem. Grigoletto and Pinheiro proposed a method without a vector involved, which has the ability to eliminate the low‐frequency oscillation, while it increases the harmonic of output voltage. Song et al proposed a reasonable function‐time distribution of positive and negative vectors to balance the neutral‐point potential.…”

The neural‐point‐clamped (NPC) three‐level inverters exhibit a midpoint potential unbalance problem. With the analysis on the midpoint potential fluctuation, its voltage vectors are discussed, and the mathematical model of the midpoint current in each sector is established. Based on virtual space vector pulse‐width modulation (VSPWM) calculated in the gh coordinate, a balance control method is proposed to compensate the midpoint potential. The virtual medium vector and voltage adjustment factor are introduced. Different positive and negative short vectors are distributed to different adjustable parameters to improve the influence of short vectors on the midpoint potential. The experimental results show that the proposed method balances the midpoint potential effectively, and VSVPWM with the gh coordinate can reduce the complexity of the calculation.
