The predictive current control method is often used in active power filter (APF), but this method has the problem of current compensation delay, and the filter itself also has periodic steady state error. In order to solve the above problems, a predictive current control method based on dead-beat repetition control is proposed. Through Matlab/Simulink simulation experiments, it is verified that this method has good compensation effect in 400Hz APF.
