内容:
为了解决NPC三电平中点电容电压的不均衡问题,得到很好的电流波形,使用基于虚拟空间矢控制方法,采用IGBT为主开关器件搭建了三电平逆变器系统平台,利用MATLAB/Simulink对中点电压均衡控制的效果进行了仿真研究。通过仿真和实验验证了此控制方案具有很好的实际效果。 In order to solve the problem of nonuniformity of the three-level mid-point capacitor voltage of NPC, a good current waveform is obtained. Based on the virtual space vector control method, a three-level inverter system platform is built by using IGBT as the main switching device. Simulink's simulation of the effect of mid-point voltage equalization control is carried out. The simulation results show that this control scheme has a good practical effect.
