Nonlinear Control Strategy of Split-Capacitor-Type Shunt Active Power Filter Based on EL Model

摘要

A hybrid PBC strategy for 2C SAPF has been proposed and implemented in this paper. The observed performance has demonstrated the ability of the proposed strategy of 2C SAF to compensate the current harmonics effectively under varying loads and unbalanced power supply. It has also been shown that the proposed strategy has a faster and better dynamic response than traditional strategy and is able to keep the THD of the supply currents well below the mark of 5% specified in the IEEE-519 standard.
