逆变电源瞬时反馈控制方法的研究

文中对逆变电源各种瞬时值反馈控制方法进行了对比研究，带电感电流内环的电压瞬时值反馈要获得与电容电流内环瞬时值反馈控制的效果，必须引入负载电流前馈；带电压微分内环的逆变电源控制系统与带电容电流内环的逆变电源控制系统相比，在理论上两种控制方案是等同的。

Study on Instantaneous Feedback Control Strategy for the Inverter Power Supply

This paper compares several schemes of output voltage instantaneous feedback control. The results show that load current feed-forward is needed in the instantaneous feedback with inductance current as the inside feedback loop, in order to reach the equal control effect with capacitor current as the inside feedback loop. Theoretically, the two control schemes that one is with output voltage differentiation as the inside feedback loop and the other with capacitor current as the inside feedback loop are equivalent.
