DPC controlled three-phase active filter for power quality improvement

This paper presents a new control method entitled direct power control (DPC) for shunt active power filtering (5th, 7th, 11th, …) (SAPF), which is applied to eliminate line current harmonics and compensate reactive power. Its main goal is to rebuild active and reactive powers to be compared to refer...

Description
Summary:This paper presents a new control method entitled direct power control (DPC) for shunt active power filtering (5th, 7th, 11th, …) (SAPF), which is applied to eliminate line current harmonics and compensate reactive power. Its main goal is to rebuild active and reactive powers to be compared to references values using hysteresis control. The outputs of hysteresis controllers associated with a switching table, control the instantaneous active and reactive power by selecting the optimum switching state of the voltage source inverter (VSI). A theoretical analysis with a complete simulation of the system and experimental results are presented to prove the excellent performance of the proposed control technique.
