The analyzed topologies of the three-phase inverters were configured to supply a three-phase inductive load (10-Ω resistance in series with 5-mH inductance) from a low-voltage dc supply; an input dc voltage or Photovoltaic Panel of 100 V was assumed for the simulation, whereas 20 V was used in the experimental design.
The comparative simulation analysis highlights the potential of these advanced inverter designs for transformerless photovoltaic systems and other renewable energy applications.
The ST states are generated by employing seven unique combinations of the B6 bridge, which allow the inverter to momentarily short-circuit the bridge, thus storing and releasing energy from the impedance network to elevate the output voltage.
Z-source inverters (ZSIs) that provide boosting and inversion in a single stage have recently gained attention owing to their reduced size, cost, weight, and system complexity compared with their two-stage equivalent 4, 5. The ZSI topology serves as the foundational circuit for many recently developed single-stage topologies.
