Detailed Description

Defines the Orthogonal Signal Generator SPLL_1PH_SOGI_FLL structure.

The SPLL_1PH_SOGI_FLL can be used to generate the orthogonal signal from the sensed single phase grid voltage and use that information to provide phase of the grid voltage This module also runs a frequency locked loop for adjusting the the center frequency automatically
