“…Third operating mode: In the steady-state, 1 S and 2 S , and 1 D are off, thus the sum of 1 L and 2 L current is negative and flows through 2 D . In this operating mode, the voltage across 1 L is positive and constant, therefore, current through 1 L increases linearly and also energy of that increases.…”

“…Due to this fact that the sum of inductors current is positive, thus, 2 D is off and 2 S is on. At the start of the second operating mode, the voltage and current of 2 S is zero, thus, this switch turns on with ZVZCS, which causes a decrease in power losses.…”

-In this paper, a bidirectional topology for quasi-Cuk dc/dc converter with capability of zero-voltage and zero-current-switching (ZVZCS) is proposed. The bidirectional quasi-Cuk (BQ-Cuk) converter has different voltage and current transfer ratio, reduced voltage stress on capacitor and capability of changing the output polarity in comparison with conventional bidirectional Cuk converter. In this paper, steady-state analysis of the quasi-Cuk converter with capability of ZVZCS in turn-on is presented. Then, critical inductances for transient from this operation to two new operations are calculated. Next, besides values designing of used elements, maximum and minimum value of their current and voltage are calculated. Finally, experimental results to verify the accuracy of the proposed converter in different operating modes are presented.

Summary Distributed generation (DG) is an important technology for increasing penetration of renewable energy sources (RES) and thereby reducing oil use and coal‐related emission. In addition, there has been recent renewed interest in multifunctional photovoltaic inverter due to its uniqueness to provide ancillary services while increasing device utilization factor. In this context, a combined active power‐sharing and grid current distortion enhancement‐based approach is proposed in this paper for three‐phase four‐wire (3P4W) grid‐connected solar photovoltaic (SPV) system. The DG is uniquely controlled by multifunctional photovoltaic inverter to autonomously acquire the following multifunctionalities: (a) active power‐sharing feature to govern the power flow between the SPV unit and utility grid based on the availability of active power at direct current (DC)–bus terminal; (b) shunt active power filter (SAPF) with functionalities of source current harmonic attenuation, load reactive current compensation, and zero sequences harmonic component mitigation, in addition to unity power factor (UPF) operation; and (c) to supply constant power to the electrical loads during solar intermittency. The proposed control systems of the DG mainly consist of the fundamental load current decomposition (FLCD) loop, active and reactive power components extractor, and source current balancing compensator. By adopting the proposed FLCD‐based approach, the fundamental load current is precisely detected while diminishing the computational intensiveness. In this study, an incremental conductance (INC)–based maximum power point (MPP) tracker has been realized using an Arm Cortex M4 microcontroller (STM32F407VGT). The multifunctionalities are demonstrated through exhaustive MATLAB/Simulink simulation results and are also validated by developing a laboratory prototype using dSPACE 1104 control platform.

Summary The increased usage of nonlinear loads in the distribution system network with deep integration of renewable energy sources imposes the need for advanced control to improve power quality. With the objective to attain desired sinusoidal voltage waveshape at the common utility point, unity power factor operation, and reduction in harmonics, a swarm intelligent enhanced dual extended Kalman filter (DEKF) control technique for improving the performance of shunt active power filter (SAPF) is proposed in this paper. A photovoltaic (PV) array is integrated at the DC‐bus which supplies the required load power thus reducing the grid power demand. A single sensor‐based control is used to track the maximum power from the two‐stage PV array. The enhancement of the SAPF performance requires proper tuning of parameters; constriction factor‐based particle swarm optimization (PSO) is adopted in this regard. The DEKF estimates both state and parameter from the nonlinear system for generating a reference signal. The performance of the proposed control algorithm is compared with the Extended Kalman filter (EKF)‐based PV‐SAPF system using MATLAB/Simulink. To verify the efficacy of the controller, an experimental PV‐SAPF prototype is developed in the laboratory and tested under balanced and unbalanced supply, dynamic load as well as varying irradiance conditions.
