“…It has terms at the same frequencies as the input power as well as terms that vary at other grid-frequency harmonics. Due to the low bandwidth of the outer voltage loop, only the low-frequency terms in (9) are required for the control design. These low-frequency terms are derived by averaging (9) over one-half of the grid period d dt…”

“…As an alternative, the indirect method generates a sinusoidal reference signal by means of grid-voltage sensing. In that case, the grid current is forced to follow this sinusoidal signal, and thus, the load harmonics are indirectly given by the APF inductor current [9]- [12]. The main advantages of this second approach are that only one low-bandwidth current sensor is required and faster transient response is obtained [12].…”

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.

“…The controller can act in any convenient domain. The design of a current-regulated PWM system is described in [78] for closed loop control of grid currents in a single-phase APF. Control in the dq0 domain including feed-forward of the AC voltage is combined with SVM in [47].…”

Filters 1 AbstractThere have been many variants of the active power filter proposed and these variations cover both the circuit topology and the control system employed. Some of the control variants reflect different control objectives but there are still many variants within similar objectives. This paper describes and contrasts the available control techniques in a structured way to identify their performance strengths. Objectives are classified by the supply current components to be corrected and by the response required to distorted grid voltage. The various signal transformations are described in terms of their impact on the distortion identification problem. Time-domain, frequency-domain, instantaneous power and impedance synthesis methods are examined. Additional control functions such as DC-bus voltage and current reference following are also discussed. It is found that a key difference between control methods is way in which current distortion is treated in the presence of distorted grid voltage.

This paper deals with a study of a shunt Active Power Filter (APF) applied to two-phase, threewire electricity networks using the Single-Phase p-q Theory. An alternative single-phase a-αβ transformation which improves instantaneous power calculations is proposed. The compensating filter currents calculations in two-phase, three-wire shunt APF are described in both direct and indirect methods using the proposed a-αβ transformation. Computational simulation results confirm the effectiveness of the proposed shunt APF in compensating current harmonics and reactive power in two-phase, three-wire loads, even under a distorted supply voltage condition.
