In several electrical dc–ac power conversions, the ac output voltage is higher than the input voltage. If a voltage-source inverter (VSI) is used, then an additional dc–dc boosting stage is required to overcome the step-down VSI limitations. Recently, several impedance source converters are gaining higher attentions <xref ref-type="bibr" rid="ref1">[1]</xref>, <xref...
Grid-connected power conversion systems for renewable energy sources must fulfill several requirements, including high efficiency, reduced cost and complexity, and, quite often, also boost capabilities from the dc sources to the ac power grid. For such applications, single-stage power converters with boost capabilities offer some potential advantages. Among several proposed options, split-source inverter...
This paper studies the integration of the two-level split-source inverter (SSI) concept into the three-level diode-clamped inverter configuration. The proposed three-level diode-clamped-based SSI (3L-DC-SSI) uses two isolated dc sources, two inductors, two capacitors, and six input diodes with the three-level diode-clamped bridge. This topology introduces lower current stresses of the switches compared...
Split-source inverter (SSI) topology is one of the recently proposed single-stage dc-ac power converters, which has some merits compared to other equivalent topologies. The SSI was proposed as a two-level topology. Hence, this paper extends its operation from two level operation to a three-level equivalent using the standard three-level flying capacitors voltage-source inverter (VSI) bridge. The extra...
Single-stage DC-AC power converters are recently gaining higher popularity due to their features in terms of size, cost, weight, and complexity of the whole system. Different topologies exist, where the Z-source inverter, the buck-boost voltage source inverter, and the Y-source inverter are the common topologies. This paper proposes another single-stage DC-AC power converter, called the split-source...
