1-phase PLL in Simulink PowerSystems blockset by Pierre Giroux

Hi Everyone,

I'm currently using PLL available from matlab simpowersystems to simulate 1-phase inverter for PV connected to grid system. There are 3 Outputs from this PLL model: freq, wt, and sin_cos in vector form. Does anyone know why output of sin_cos? The sin_cos only shows the sin_cos signal without taking consideration of the signal amplitude? I'm actually trying to figure out where's the Vout of the Phase-locked loop, is it sin_cos?

Thanks
