Novel PLL for power converters under unbalanced and distorted grid conditions

Novel PLL for power converters under unbalanced and distorted grid conditions

A novel phase-locked loop (PLL) with simple structure is proposed in the present work for three-phase power converters under adverse grid conditions. Based on a synchronous rotating frame PLL (SRF-PLL), multi-resonant harmonic compensators with the ability of accommodating frequency deviations are e...
