| 摘 要： | 对于单相400 Hz 逆变器，提出了一种电感电流反馈的双环控制方案。通过把负载电流处理成扰动，建立了单相逆变器的数学模型。双环控制利用输出电压解耦和输出电流回馈来消除扰动，通过对内外环的比例参数整定来得到理想的输出波形。受开关频率的影响，系统带宽有限，双环控制器主要用于减小低次谐波畸变。仿真结果显示双环控制器能够使400Hz逆变器产生较好的稳态输出电压。

| Abstract: | In this paper,a dual-loop control scheme for single-phase 400 Hz inverters is presented.The mathematical model of single-phase inverter is established with the load current being treated as a disturbance.It uses a dual-loop control of the output voltage and output current decoupling feedback to eliminate disturbance.Through the turning of the inside and outside rings proportion parameters,we get an ideal output waveforms.By the impact of switching frequency,the system bandwidth is limited.A dual-loop contro... |
