“…This model must be accurate enough up to half the switching frequency in order to correctly describe the APF frequency characteristics. Some approximate models can be found in the literature [35], [36], but an exact model for frequencies higher than the grid frequency is not available yet. As an alternative, this paper uses simulation tools in order to design this control loop.…”

Abstract-This paper presents a linear current control scheme for single-phase active power filters. The approach is based on an outer voltage loop, an inner current loop, and a resonant selective harmonic compensator. The design of the control parameters is carried out using conventional linear techniques (analysis of loop gain and other disturbance-rejection transfer functions). The performance of the proposed controller is evaluated and compared with two reference controllers: a basic control and an advanced repetitive control. In comparison with these controllers, the proposed control scheme provides additional attenuation to the harmonics coming from the load current, the grid voltage, and the reference signal, resulting in a grid current with lower harmonic distortion. Experimental results are reported in order to validate this paper.

“…This voltage is equal to the grid voltage. The influence of grid voltage fluctuation on DC-link voltage can be eliminated by applying the feed-forward control strategy proposed in [26]. Thus, the following derivations based on the balanced, three-phase grid voltage system simplify calculation and deduction to establish the DC-link voltage control loop.…”

This study investigates the inherent influence of a DC-link voltage controller on both DC-link voltage control and the compensation performance of a three-phase, four-wire shunt active power filter (APF). A nonlinear variable-parameter DC-link voltage controller is proposed to satisfy both the dynamic characteristic of DC-link voltage control and steady-state compensation performance. Unlike in the conventional fixed-parameter controller, the parameters in the proposed controller vary according to the difference between the actual and the reference DC-link voltages. The design procedures for the nonlinear voltage controller with variable parameters are determined and analyzed so that the proposed voltage controller can be designed accordingly. Representative simulation and experimental results for the three-phase, four-wire, center-spilt shunt APF verify the analysis findings, as well as the feasibility and effectiveness of the proposed DC-link voltage controller.

“…They may cause resonance and the impedance of the power system strongly affects the filtering effects. To overcome these disadvantages, Active Power Filter (APF) has been proposed [3][4][5][6][7][8]. A novel principle of magnetic flux compensation (MFC) is proposed in reference [7], which has been applied in series hybrid APF [7][8], controllable reactor [9], and shunt hybrid APF [10].…”

-In the series hybrid active power filter (SHAPF) with magnetic flux compensation (MFC), the system current oscillate in the experimental results when adding the same phase harmonic current command in current control block. This condition endangers the security of the SHAPF. Taking the digit period average arithmetic as example, this paper explains the inter-harmonics current oscillation in the experiment. The conclusion is that the SHAPF is unstable to the inter-harmonics current in theory. Limited by the capacity of the inverter, the system current and the inverter output current do not increase to infinite. At last, some methods are proposed to solve this problem. From the practical viewpoint, the voltage feed-forward control is easy to achieve. It can suppress the current oscillation problems, and also improve the filtering effect. The feasibility of the methods is validated by both the emulation and experiment results.
