About Phase Locked Loop Modules(SPLL_1ph_CLA_C.h).

Dear all.

I have some questions.

I was simulated to use the PSIM about Phase Locked Loop Modules.

Simulation result is below Figure 1.

          Figure 1. input: Vac_in(-0.7 ~ 0.7), Output: Theta1(0 ~ 0.474), Sin1(-0.99 ~ +0.99) and cos1(-0.99 ~ +0.99).

Figure 2. Module interface definition.

For the simulation, I was using "SPLL_1ph_CLA_C.h" and "CLA C Solar Library.pdf (v1.1)".

My Questions.

1.  Is this result correct?

2. v.theta0 = v.theta1 + (v.wn * SPLL_1ph_CONST_1);

   SPLL_1ph_CONST_1 = 0.00000795;

   here, What does mean SPLL_1ph_CONST_1(0.00000795)?

3. Figure 2. Module interface definition.

   Accepthable Range of theta is float32(-2*pi ~ 2*pi). but theta range of Figure1 is 0 ~ 0.474.

   My opinion:

     theta range of Figure1 :  maybe 0 ~ 2*pi.  Is this correct?

4.  interrupt void Cla1Task1(void) {

     ....

     // SPLL call

     spll1.AC_input  =  Vac_in;

     SPLL_1ph_CLA_C(spll1);

     InvSine = (spll1.sin0);

     .....

}

    what are the "InvSine" used?

Thank you so much your interest.
