In this presentation a Resonant Control strategy for a Gird Connected Converter is studied in a variable frequency grid. The simple implementation of a resonant controller and the well defined spectrum make this application interesting. However, variable frequency grids make the tuning a challenge because the resonance would not be fixed. Yet, depending upon the sampling frequency, it is not necessary to adapt the resonant controller’s parameters as a function of the ac grid frequency, but only the sampling time.
