文摘
- •
A harmonic detection method applied in single-phase PV inverters is proposed.
- •
The harmonic detection method is based on second order generalized integrator.
- •
The higher harmonic component with higher amplitude is detected.
- •
The detector action depends of the SOGI-PLL detection zone.
- •
The harmonic detector tunes the frequency of the resonant controller dynamically.
