摘要

In this paper, the digital realization theory and key technologies of Multi-level SPWM scheme implementation for the three-level Neutral Point Clamped (NPC) inverter is presented. The digital asymmetrical regular sampling principle of SPWM is realized with only a single FPGA chip LFEC10 from LATTICE Inc. and the programming language is Very High Speed Integrated Circuit Hardware Description Language (VHDL). This full digital circuit can provide an effective, flexible, and safe solution for high-power inverts. At last, some simulation and experimental results have been presented and discussed in this paper.
