Since you are modeling an AC-DC converter, the paper, __Modeling of Three-phase Controlled Rectifier using a DQ Method__, by K.Chaijarurnudomrung, K-N. Areerak, and K-L. Areerak, may be useful.

The authors did not use PSCAD in their simulation, but they do provide mathematical relationships between input and output that will help you obtain answer to your question.

The paper includes three equations (3)-(5): (3) represents the basic dq switching function used [**S abc**]; (4) is the current relationship between input and output [**I in,abc** = **S abc** I dc]; and (5) is the relationship between DC output voltage to the AC input voltage [Edc = **S^T abc V bus, abc**]**. ** The authors also include a list of references that may prove useful to you.

If there are specific details you can share about performance objectives, along with details about the power electronics you used in your model, that would useful. The referenced paper used silicon-controlled rectifiers (thyristors).
