摘　　要：为了提高逆变器的动态性能，改善输出电压波形质量，应用了具有电流反馈内环和电压反馈外环相结合的双闭环控制技术。内环用于改善系统的动态性能，迅速地消除负载扰动的影响；而外环则用于改善系统的稳态性能。本文通过Matlab／Simulink对系统进行了建模，验证了双闭环控制结构的可行性。In order to improve the dynamic performance of the inverter and the waveform quality of the output voltage. The dual closed-loop control technology of combining the inner loop of current feedback with the outer loop of voltage feedback is applied. The inner loop is used for improving the dynamic performance of the system and rapidly eliminating the effects of load disturbance; but the outer loop is used for improving the steady-state performance of the system. Finally. Matlab/Simulink is used for the system modeling and the feasibility of the dual closed-loop control structure is verified in this paper.
