Error in Activate (Modelica Block)

Hi All!

I am using the Power Converter block DCAC (Multiphase Inverter).

I am getting the below error while running the simulation:

[ThreePhaseInvertre]: Error: Error, (in MapleSim:-Modelica:-Flatten) in `vss_ThreePhaseInvertre_im.container.subcontainer` connecting scalar to array in connect(BooleanPulse.y,inverter.fire_p)

( 99 )

Block(s): connecting scalar to array in connect(BooleanPulse

Model: ThreePhaseInvertre

As far as I understand, I am not able to connect the Gating signals at inverter, neither using the singal boolean signal or using MUX to give pulses.

Can anyone guide me how to give pulses to this inverter block.

Thanks,

Sangeet

Hi Sangeet,

You just have to set type Vector and size 3 in ToModelica. The inputs are expected as vectors of size m, basically 3.

Thanks, the way you suggested worked.

I would also like to know how can I saperate the 3-phase AC signals generated, to connect to a load or voltage sensors.

Thanks

If you use the multiphase sensor you get the 3 phases in one vector signal

If you want to handle the phases separately, the demo Modelica/Electrical/QuasiStationary/MultiPhase/Unsymmetrical load.scm in demo browser shows how this can be realized.

Hi Sangeet,

on top of what Ronald has shown in the previous posts, you can also get inspiration from the demo/Modelica diagrams content.

As an example, the Modelica/Blocks/PID_Controller.scm demo illustrates how to take advantage of a ModelicaExtras/Routing/VectorScalar block that can do the job in this case.
