Resumen:
In this paper a sensorless current control for grid connected inverters is presented. The use of a grid voltage sensor is avoided, estimating the fundamental component and the harmonic content of the grid voltage via a reduced order observer. The proposed observer is frequency adaptive. The current control scheme is realized through a proportional resonant algorithm, using a scaled version of the estimated grid voltage fundamental component as current reference. The control algorithm is made frequency adaptive using the estimated frequency provided by the proposed observer. Simulation results are presented to validate the proposed scheme.
