HERIC = highly efficient and reliable inverter concept; MLI = multilevel inverter; MPPT = maximum power point tracking; NPC = neutral point clamped; PV = photovoltaic; QZSI = Quasi-Z-source inverter; THD = total harmonic distortion. This comprehensive table presents recent developments in grid-connected inverter topologies (2020–2025). 4.
An inverter is a crucial component in grid-connected PV systems. This study focuses on inverter standards for grid-connected PV systems, as well as various inverter topologies for connecting PV panels to a three-phase or single-phase grid, as well as their benefits and drawbacks.
There are different inverter topologies used for single phase or three phase grid connected PV systems like central inverter, string inverter, multi-string inverter, and module integrated microinverter according to their architecture or arrangement of PV modules interface with inverter and grid.
The multi-frequency grid-connected inverter topology is designed to improve power density and grid current quality while addressing the trade-off between switching frequency and power losses . Traditional grid-connected inverters rely on power filters to meet harmonic standards, but these filters increase system complexity, cost, and size.
