【Abstract】 The characteristic of analog control of PWM inverters is analyzed and an analog control scheme of PI dual-loop is applied. The parameters of control system are designed by the method of pole assignment. Simulation analysis demonstrated the feasibility. At last, the experiment waveforms were presented. The experimental results demonstrated that the design process of this scheme was easy and the system could achieve good dynamic and static performance.更多还原
