“…Topology discussed in [27] is three-phase MOCs able to produce unregulated three-phase multiple AC outputs with no DC at the output. Hybrid MOCs discussed in [28] can produce a single DC and three-phase AC output simultaneously from a single DC input. Both the DC and three-phase AC outputs can be independently regulated.…”

In this paper, two (series and parallel versions) quasi Z source inverter (qZSI)-based multioutput series-parallel topologies capable of supplying multiple three-phase AC and single boost DC outputs simultaneously are presented. The proposed parallel version topology can supply n number of AC outputs along with one boost DC with constant voltage and variable current. Similarly, the series version topology can give n number of AC including one boost DC output with constant current and variable voltage. The outputs of the proposed topologies can feed directly to DC/AC microgrids and multiple residential loads simultaneously without using any extra adapter/regulator and thereby avoiding local power conversion to meet the load demand. A hybrid pulse width modulation technique with constant frequency is used to operate the proposed topologies. The performance of the proposed topologies is verified by developing the prototypes of 2.18 kW (for parallel version) and 2.02 kW (for series version) for two three-phase AC outputs and one boost DC output. The developed prototypes show measured efficiency of 90.01% for the parallel and 89.95% for the series version topology.

This study proposes a novel buck-boost based interleaved hybrid converter (BIHC), which can supply both AC and DC loads simultaneously. This topology uses two buck-boost derived hybrid converters where the DC outputs of the individual converters are interleaved and the AC voltage is the differential voltage tapped between the two source (of the MOSFETs) nodes of the individual converters. This converter uses only two switches which is lower than similar converters reported in literature, hence reducing the switching losses. In BIHC, there is no possibility of shoot through and no dead time compensation is required. BIHC will find application in hybrid nanogrids supplying residential loads powered by solar photovoltaic. The principle of operation of individual converters is augmented sinusoidal pulse width modulation with AC references for individual converters phase shifted by 180°. This results in line frequency components in the inductor currents and hence the buck-boost stage inductors are relatively larger. However, reduction in number of switches offsets this increase in size. The circuit has been extensively simulated in MATLAB and an experimental prototype of 100 W is tested in the laboratory.

“…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.…”

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.
