Real-time waveforms of three-phase source/grid currents and DC-link voltage under varying irradiance levels (600–1000 W/m²) with a fixed non-linear load—(a) waveforms under balanced PCC voltage condition, and (b) waveforms under unbalanced PCC voltage condition. CH1 to CH3: source/grid current waveforms (5 A/div); CH4: DC-link voltage (200 V/div).
