Hello,
The problem appears to be with the generation of the three-phase reference signals. You should use a Sine Wave block to generate the reference or use the wrapping feature of the Integrator, rather than the Memory block for this purpose (which can have unintended effects). Please find attached a modified version of your circuit with balanced phase currents.
Best,
Kris
