“…In [20,21] the conventional single band hysteresis current-control (SBHCC) scheme is used showing good accuracy and quick response, but the high switching frequency results in high switching losses. To overcome the problem of high switching frequency an adaptive hysteresis current-control [22] and double band hysteresis current control [23] are proposed.…”

The increased use of non-linear loads results in more harmonics content in the source current. Shunt active power filters are used for correction of distorted source current by injecting a compensating current in parallel to the load current. The injected current will shape the supply current to a sinusoidal. In this paper an improved performance of shunt active power filter is achieved by using sliding mode controller for generation of gate pulses of voltage source inverter. The implemented control technique has been evaluated and compared with hysteresis current control. The performance parameters used for evaluating the shunt active power filter are total harmonic distortion, power factor and harmonics compensation ratio. The simulation results show excellent performance of active power filter in terms of harmonics mitigation and dynamic response. Experimental tests are also performed using NI DAQ card in Labview environment to validate the simulation results. Both the simulation and experimental results prove good performance of sliding mode control for accurate injection of reference current.

“…But, the major limitation of the HCC is its highly variable switching frequency to match variation in solar irradiation and associated compensation requirements that results in higher switching losses. To overcome the drawback of high variable switching frequency, advanced HCC methods are described in the literature [29][30][31]. A variable double-band (VDB)-HCC concept is presented in [30] for single-phase full-bridge bi-directional converters.…”

Integration of rooftop solar-PV (RTSPV) systems and extensive use of nonlinear loads in the low-voltage distribution system (LVDS) leads to poor power quality (PQ). Therefore, it is necessary to address the issues leading to poor PQ at the point of common coupling of the LVDS. In this article, a multi-band hysteresis current control (MB-HCC) for the multi-functional inverter (MFI) is proposed which improves the efficiency of the MFI and also enhances the PQ of the LVDS. The MB-HCC uses simple switching logic and outperforms in its multi-functional tasks such as active power injection and power conditioning. MB-HCC offers better efficiency over variable double-band HCC (VDB-HCC) as it operates at a lower switching frequency. The performance of the proposed system is simulated by using MATLAB/Simulink and validated by OPAL-RT based real-time simulation studies. During the variation of solar irradiation, the proposed MFI has an average efficiency of 98.5% under the ideal grid and 97.34% under the distorted grid. Moreover, the percentage of Total Harmonic Distortion under ideal and distorted grid conditions is brought down to below 5%, and also, reactive power compensation maintains unity power factor operation complying with the IEEE-519-2014 and 1547 standards. These results substantiate the hypothesis of scalability of the single-phase MB-HCC-based MFI for an LVDS contributing to economy and ecology.

“…In order to reduce the losses, a compromised hysteresis band has to be chosen. Therefore, in Komurcugil, the double‐band hysteresis controller is proposed for single‐phase shunt active filter to control the reactive power. For the first time in this work, the double‐band hysteresis controller is introduced in 3‐phase CCVSI to control the real power in addition to the reactive power.…”

Summary With the advancement of power electronics and control techniques, the renewable energy sources are integrated to the grid through highly efficient power electronic interfaces. The voltage source inverter connected at the grid acts as shunt active power filter to mitigate the power quality issues in addition to the power conversion. In this paper, the double‐band hysteresis current controller is implemented to ensure the real and reactive power flow from renewable energy system (RES) to the grid through voltage source inverter. In order to show the efficacy of the controller, 3 different modes depending on the climatic conditions such as (1) no RES power, (2) lacking RES power, and (3) surplus RES power are taken into consideration. The synchronous detection method with equal current criterion is used to generate the reference current. This criterion makes the grid currents balanced and sinusoidal even under unbalanced grid voltage conditions. The control system guarantees the unity power factor in the grid side with reduced total harmonic distortion in the presence of nonlinear loads. The average switching frequency is also reduced using double‐band hysteresis current controller which is proved by simulation, and the performance of the system is validated with the experimental results.
