“…Therefore, to equalize or interface the motor and battery, a high-gain DC-DC bidirectional topologies are investigated in earlier literature. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] Due to its bidirectional power flow capability, these converters help to store regenerative energy into the battery at the time of braking.…”

“…The bidirectional DC-DC converters are categorized into two types based on the configurations, such as isolated DC-DC converters [9][10][11][12] and non-isolated bidirectional DC-DC converters (NBDC). [13][14][15][16][17][18][19][20][21][22][23] Flyback converter, 9 SEPIC, 10 full-bridge converters, 11 and multilevel-type converter 12 are various topologies of isolated converters in the earlier literature. These DC-DC converters are less complicated to control due to their simple configuration.…”

In electric vehicle (EV) onboard applications, the bidirectional DC‐DC converter is proposed in this paper to interface low terminal voltage battery with DC bus of the motor. The proposed bidirectional DC–DC converter is configured based on a ladder switching network of inductors and a capacitor. Due to this configuration, the proposed converter has a simple structure, and it can archive high voltage gain with fewer components. A detailed comparative analysis is presented to verify the uniqueness and superiority of the proposed topology. Furthermore, the detailed steady‐state analysis and working principles are presented in this paper. Finally, the 300‐W prototype is built, and the experimental results are presented to verify the performance and feasibility of the proposed bidirectional converter.

“…So in solar PV-based system after extracting maximum power, two different power electronics conversion stages are required to supply the hybrid loads, i.e. (i) DC-DC conversion stage to supply DC loads and (ii) DC-AC conversion stage to supply the AC loads [11][12][13][14][15]. Therefore, in conventional solar PV system delivering hybrid loads, three power electronics conversion stages (as shown in Fig.…”

“…There are many variations of the hybrid converters available in the literature [13][14][15][16][17][18][19][20] with reduced conversion stages, to generate hybrid outputs. The switched boost inverter is one of the hybrid converter proposed in [17], to generate ac and DC outputs simultaneously, to supply hybrid loads.…”

“…Boost derived hybrid converter is a step up hybrid converter which generate simultaneous AC and DC outputs using shoot through state available in the VSI. These hybrid converters as discussed in [13][14][15][16][17][18][19][20] can generate AC and DC outputs simultaneously using single DC source. So when these hybrid converters are used in the solar PV system, a DC-DC conversion stage is required for MPPT which again increases the number of conversion stages.…”

Solar PV system for off-grid applications is growing at a faster rate because of its compatibility and ease of implementation. The modern smart building consists of hybrid AC and DC loads. The solar PV system generates DC power and can also supply the DC loads. To supply the AC loads, the DC power need conversion to AC using a DC-AC converter. A general solar PV system consists of two stages, one is to extract the maximum power and the other one is to convert it into a suitable DC or AC. Here, a single-stage multi-functional converter (MFC) is employed, which extracts maximum power and supplies to both AC and DC loads. To overcome the intermittency of solar PV output, battery energy storage is interfaced through a non-isolated buck-boost converter. The MFC operates in two modes, i.e. hybrid power flow mode and inverter mode, depending upon the availability of solar PV output. The proposed system is simulated using the PSCAD/EMTDC software. An experimental test setup using solar array simulator and a multifunctional power electronics converter has been developed for demonstration of the results. The control algorithms are implemented using NI PXI-7842R series FPGA controller through LabVIEW platform.

Aiming to integrate distinct renewable energy sources and to obtain the benefits of quasi‐Z‐source converter, voltage doubler rectifier, and switched capacitor converter, a high‐gain multi‐input single‐output switched quasi‐Z‐source converter (SqZSC) with a multi‐input high‐frequency transformer is proposed. The proposed SqZSC fed three‐phase six‐level (TPSL) micro‐inverter is designed to integrate multiple small‐scale renewable energy sources such as wind, photovoltaic systems, and fuel cells with the utility grid. Compared with the other topology of Z‐source converter, the designed converter can offer a high boost factor, low conversion losses, low voltage and current stress across the main chopping switches, and the one‐port impedance network. The design, working principle, voltage and current stress of the chopping switches, experimental results, and comparison with the other topology of ZSC are presented. Finally, the results of a 1200‐W prototype model are given to authenticate the steady‐state and dynamic performance of the proposed multi‐input single‐output SqZSC.
