High-Frequency Current Ripple Sample Anti-Aliasing Strategy of Digitally Controlled Converter Based on Notch Filter
The digital controller of the grid-connected converter achieves closed-loop control by sampling key voltage and current signals. High-frequency switching of power electronic switches introduces high-frequency ripples into the signals, which may cause sampling aliasing. Severe distortion may happen i...
