title = "A new high control precision active power filter",
abstract = "With the increasing use of electrical equipment, the harmonic pollution and electromagnetic interference of the power grid are becoming increasingly serious. In order to reduce the harmonic pollution of the power grid and meet the requirements of some EMC (25Hz-5kHz) occasions, a new high control precision active power filter is developed in this paper. In order to improve the compensation precision of active power filter, the closed loop control of active power filter based on DQ axis is adopted in this paper. Through the real-time detection and the control of the harmonic current of the grid side, the closed loop control can achieve no error. The analog proportional control is used to improve the dynamic response speed and the steady state tracking effect of the system. At the same time, the digital repetitive control is adopted. The zero error tracking of the AC signal is realized by the principle of the inner membrane. The validity of the proposed control strategy is verified on a 10A APF prototype, and the compensation test results meet the requirements of EMC (25Hz-5kHz).",
