    Three SPLL (Software Phase Lock Loops)that differ by the method of the detection of symmetrical grid voltage sequences (positive and negative ones) are presented. Simulation and experimental results of these SPLL applied in a three-phase PWM rectifier connected to an unsymmetrical grid voltage system with harmonics are discussed, even under some disturbances and parameter changes of the grid. The function of the DSC (Delayed Signal Cancellation) based SPLL in PWM rectifier with fs = 1600 Hz was experimetally verified under different grid voltage disturbances with satisfactory results.
