逆变器电容和电感电流反馈方式的比较研究

Comparative Research on Sine Wave Inverters with Inductor Current and Capacitor Current Regulation

研究了以电容电流作为反馈量的逆变器电流滞环控制方法,提出实现电路,并从理论、仿真和实验的角度与传统的电感电流反馈方式作比较。研究表明,采用电容电流反馈控制方式,可以使逆变系统的输出电压波形及负载特性得以有效改善。

The output filter capacitor current is implemented in the inner current control loop. Theoretic analysis, simulation and experiments are carried out between capacitor current feedback and inductor current feedback control methods for the inverter prototype. The conclusion is that both output voltage waveform at rectifier load and system output characteristic may be improved apparently with capacitor current feedback regulation.
