“…For showing how the current flows in different operating states, the current paths for identified switching states given in Figure 7 are presented in Figure 8. It is noted that since there are 2 7 valid switching states for a seven-leg converter, showing all operating conditions is not feasible. Therefore, only some simultaneous and nonsimultaneous states are considered.…”

“…This triggers the research in the direction of the multiport converters (MPCs). 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, 8–10 (b) AC MPCs, 11–13 and (c) hybrid MPCs 14–17 .…”

“…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.

“…Multi-input DC-DC converters allow energy from one or multiple sources to be shared with the load. Control signals of multiple converters should be synced because they are not self-contained [6][7][8][9][10]. Following the studies on controllers for DC-DC converters, extensive research on Kalman filter with power electronic converters emerges [11][12][13][14].…”

Renewable energy system (RES) based microgrid applications have grown extensively over the recent years. Owing to power fluctuations in RES, acquiring stable and accurate output voltage at the DC Bus is a major concern in DC microgrid applications. Presently, switching, as well as, prediction of output voltage for RES is quite slow and total harmonic distortion cannot be reduced to a minimal level. Accordingly, this research developed a controller for Multiple Input Single Output (MISO) DC to DC converter and a Kalman filter. Initially, four seriesconnected PV panels were modelled and analysed. A boost converter was used to combine PV panels' output and provide a single output at the DC Bus. Perturb and Observe, a Maximum Power Point Tracking (MPPT) algorithm, was used to retrieve optimal power from modelled RES. Analysis revealed that the output voltage waveform contained harmonics and had a Total Harmonic Distortion (THD) of 27.73 %. Thus, a Kalman filter was modeled and analysed to remove the harmonics. The THD value was consequently reduced to 2.1 %, which is quite within the allowable limit prescribed by IEEE, for the THD of a PV system. Analysis revealed that a stable and accurate output from a PV based RES could be achieved with the proposed scheme, and further THD was also well within limits prescribed by IEEE.

“…However, the variety of renewable energy sources and varied power converters complicates their penetration. The DC-DC converters are usually application-specific and suitable for low to high-power applications in Electric Vehicles (EVs) and grid-tied converters [1][2]. The automotive industry, as well as many national governments, have recently promoted and invested significant resources in developing EVs and hybrid electric vehicles (HEVs) to reduce dependency on fossil fuels while providing users with energy-efficient, environmentally-friendly transportation.…”
