Research of Three-phase Shunt Active Power Filter Design Method

In this paper,the system circuit and the principle of a shunt active power filters are introduced. The cal- culation of harmonic current based on three-phase instantaneous reactive power theory and hysteresis current tracking control strategy are analyzed. The model of APF is established by Matlab and the sim- ulation of different parameters is given. The simula- tion shows that the control strategy is correct. The APF can compensate harmonic current and improve the power quality effectively.
