摘要：
Resonant parts can be used in current controllers to suppress harmonics. However, they may cause destabilization of poorly damped grid and/or input-filter resonances, particularly for a nonnegligible converter time delay. This letter presents a design method whereby destabilization is prevented by making the converter's input admittance
