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.
This dependency leads to fluctuations in power output and potential grid instability. Grid-connected inverters (GCIs) have emerged as a critical technology addressing these challenges. GCIs convert variable direct current (DC) power from renewable sources into alternating current (AC) power suitable for grid consumption .
