An improved power quality (PQ) solar photovoltaic (PV) inverter that eliminates common-mode current leakages is presented in this research. This study examines a three-phase transformer-less solar energy converting system (SECS) that, in addition to peak active power generation from PV arrays, guarantees various power quality enhancement capabilities like grid current balancing and harmonic mitigation, and provides grid reactive power support. This approach doesn't compromise the leakage currents induced by the parasitic capacitance of the PV array to ground. Unlike traditional power quality inverters, it is robust regarding anomalies in grid voltages at distant radial trimmings. PV leakage currents are often ignored in PV inverter power superiority organizations, even though the reality is that they have an important impact on system performance by degrading power quality and endangering operating staff protection. Consequently, transformer-less PV systems must activate using leakage currents within the 300 mA range as required by the principles \(VDE-00126 and NB/T-32004\) . Numerous test and simulation findings demonstrate that the suggested approach performs satisfactorily even when subjected to different grid-side anomalies. The strategy's efficacy is demonstrated by the comparison with cutting-edge methods. Under all test situations, the grid current harmonics are found to be within the \(IEEE-519\) as well as \(IEC-61727\) standards’ bounds, and the PV escape currents are kept fit surrounded by the \(VDE-00126\) standard's acceptable range.
