This paper aims to develop the recently introduced Spilt-Source Inverter (SSI) topology to improve its boosting characteristics. New SSI topologies with high voltage gain are introduced in this paper. The proposed converters square the basic SSI's boosting factor by utilizing an additional inductor, capacitor, and two diodes. Thus, the proposed converters are called Quadratic-Boost (or Square-Boost) SSIs (QBIs or SBIs). Four different QBI topologies are presented. One with continuous input current (CC-QBI), and the other draws a discontinuous input current (DC-QBI) but with reduced capacitor voltage stresses. This paper also introduces the small-signal model of the CC-QBI using state variables perturbance. Based on this model, the closed-loop voltage and current control approach of the dc-boosting factor are designed. Moreover, a modified space vector modulation (MSVM) scheme is presented to reduce the input current ripples. To evaluate the performance of the proposed topologies, a comparative study between them and the other counterpart from different perspectives is introduced. It can be found that the CC-QBI topology has superior boosting characteristics when operating with low input voltage compared with their counterparts. It has a higher boosting capability, lower capacitor voltages, and semiconductor stresses, especially when high voltage gains are required. These merits make the proposed topologies convenient to the Photovoltaic and Fuel-Cell systems. Finally, the feasibility of the suggested topology and the introduced mathematical model is verified via simulation and experimental results, which show good accordance with the theoretical analysis.INDEX TERMS Split-source inverters (SSI), quasi-z source inverters, dc-ac boost converter, space-vector PWM.

“…However, in the qZS-NSI, there are dual outputs, and the output frequencies may be equal in CF mode or unequal in DF mode. Therefore, although the average value of the ST duty cycle is the same for both CF and DF, the frequency of the fundamental component of the ST duty cycle is varying and given by (23).…”

“…Consequently, it can be found that the 3LST DM/SB scheme requires a higher inductance and capacitance than the other schemes. On the other hand, in the implementation of MB control schemes, the fundamental frequency of the impedance network 𝑓 𝑑𝑜 , given in (23), instead of the effective switching frequency should be considered. This is owed to the presentation of low-frequency (LF) components in the dc-side, as concluded in Table V.…”

“…MPCs have been taking much attention since last decade due to their capability in integrating multiple sources/loads in a cost-efficient way. 7 Depending on the type of integrated sources/loads, MPCs can be divided into three categories: (a) DC MPCs, [8][9][10] (b) AC MPCs, [11][12][13] and (c) hybrid MPCs. [14][15][16][17] As shown in Figure 2A, the DC-based RESs suffering from the intermittency are the main application for DC MPCs, where these sources are integrated with energy storage systems to create a smooth and programmable power generation at output.…”

Summary In this paper, an innovative switching scheme named simultaneous space vector modulation (SSVM) is proposed for integrating various AC sources in the energy industry using a unified multiport converter. The proposed SSVM technique is applied to the multileg topology of a multiport converter, which is an encouraging option for the grid integration of renewable energy sources and multimachine drives. Considering the shared leg in the multileg converter, the proposed SSVM can utilize the utmost simultaneous switching states between different ports, resulting in lower switching loss and better DC‐link voltage utilization compared with the conventional sequential space vector modulation approach. A novel decision matrix concept is introduced to identify the simultaneous switching states. For this aim, according to the number of ports of the multileg converter, decision matrices containing valid simultaneous switching states are first calculated. Then, they are defined as look‐up tables in the proposed SSVM to be retrieved and exploited in every sampling period. The effectiveness of the proposed SSVM for a seven‐leg version of the multileg converter is assessed using the simulation analysis and real‐time validation. The capability of the proposed SSVM‐based multiport converter in grid integration of AC renewable energy sources is also verified considering two permanent magnet synchronous generator (PMSG)‐based wind turbines with real wind speed patterns. The simulation results confirm that the proposed SSVM is properly able to manage the power flow between different ports and improve the DC voltage utilization and switching loss compared with the sequential SVM.
