Abstract :
In this paper, a practical implementation method using the recursive discrete Fourier transform (RDFT) for the reference signal generator of active power filter (APF) based on current physical components (CPC) power theory is proposed. Errors and convergence issues caused by computation or frequency deviation are addressed in details and related solutions with high computational efficiency for their elimination are given.
