Abstract
After expounding the overall design of the three-level SVPWM principle and algorithm, the SVPWM top level module using FPGA is created. And A/D conversion module, the Clarke transformation module, the adjacent vector function time module and the triangle carrier module are also established. Quartus II is used to simulation. And compared with the simulation results of MATLAB, the simulation waveforms are consistent, which verifies the correctness of the simulation results. Taking the diode clamped three-level inverter as the research object, the simulation waveforms of the different modulation M are compared, and the correctness of the three-level SVPWM control strategy is further verified.
