Abstract

This paper develops the Waveform Reconstruction Method (WRM) for high accuracy and bandwidth signal decomposition of voltage harmonic type (V-type) three-phase diode rectifier load voltage into its harmonic and fundamental components, which are utilized in the Series Active Filter (SAF) control algorithms. The SAF compensated system utilizing WRM provides high performance load harmonic voltage isolation and load voltage regulation at steady-state and during transients compared to the system utilizing the synchronous reference frame based signal decomposition. Additionally, reducing the line current sampling delay in the discrete-time implementation enhances the stability of the SAF. The simulations and experimental studies of a 10 kW three-phase SAF compensated system prove the theory.
