“…Many types have been developed for these inverters in the last two decades. These types use the passive components (inductors and capacitors) in conjunction with the semiconductors to perform the bucking/boosting and the dc-ac inversion processes [1]. It can be categorized into three basic configurations called impedance source-based inverters (ZSI), differential-mode inverters (DMI), and split source inverters (SSI).…”

Three-phase Split-source inverter (SSI) has recently been proposed as an alternative to the three-phase Zsource inverters (ZSI). This paper introduced an improved finite control set-model predictive control (FCS-MPC) algorithm for the SSI. The proposed FCS-MPC algorithm reduces the computational burden by selecting the discharging vector directly according to the current status of the inductor compared to its reference point instead of checking the other states. Moreover, it simplifies the cost function by removing the inductor current term, and thus no weighting factor is needed inside the cost function. A detailed analysis of the proposed algorithm is presented in this paper. Finally, simulation results based on MATLAB have been introduced to show the viability of the presented research and theoretical study of the FCS-MPC algorithm of the three-phase SSI under different operating conditions.

“…In the last two decades, many single-stage inverters have been developed, such as Z-source and Split-source inverters to overcome the shortcoming for utilizing an additional dc-dc converters [8]- [10], [12], [13]. These topologies can perform bucking or boosting action in conjunction of dc-ac inversion at the same time by integrating a number of passive components (inductors and capacitors) together with semiconductors [1]. There have been numerous studies on the dual output single-stage inverters [3][4][5][6][7][8][9][10][11].…”

A simplified dual-output boosting inverter topology is proposed in this study. It can be used to supply two independent single-phase loads from a low voltage DC-power supply with fewer active and passive components. The output voltages can be at the same frequency (common-frequency mode) or at different frequencies. The proposed topology uses a single inductor and capacitor to control both boosting and inversion operations. Compared to the traditional dual output inverter, the proposed topology reduces the active switches by 25%, while compared with the basic Z-source-based dual output inverter, it reduces the passive elements by 50%. The main drawback of this topology is the high-frequency current commutation problem of the forward diodes. A novel carrierbased pulse width modulation scheme to obtain sinusoidal output voltage with low input current ripples of the proposed topology is presented in this paper. Moreover, the presented topology's operating principles and mathematical analysis are introduced. Finally, a simulation study is presented to confirm the theoretical study.

SummaryIn this paper, for standalone and grid‐connected PV systems, a three‐phase simplified split‐source inverter (SSI) is proposed and controlled using a model‐predictive control (MPC). The maximum power point tracking (MPPT) approach used is an incremental conductance method based on a PI controller for both systems. The standalone system is composed of PV modules, a three‐phase SSI, and a bidirectional power DC–DC converter that connects a battery bank and a DC‐side capacitor. The output AC voltages of SSI are controlled using MPC. The bidirectional power DC–DC converter regulates the DC‐link voltage (DCLV). The grid‐connected system consists of PV modules, a three‐phase SSI, and an AC‐side L‐filter. The DC‐link PI controller generates reference currents for the MPC algorithm. The MPC uses these reference currents to adjust and deliver the PV power to the grid while regulating the DCLV. The PI controllers' parameters are selected for both systems using the Harris Hawks optimization method. Both PV systems simulation results show that under various operating conditions, they have succeeded in fixing a DCLV and producing a high‐quality AC output voltage and current at low THD. Experimental results for the three‐phase standalone PV system used to verify the system's performance.
