How to break down three phase pulses into single phase for gate pulses?

I have a gate signal controlled with PWM which is used on the gate of an IGBT converter block. There are six pulses in all. The model which is simulating the connection of a wind turbine to the grid with full size converter works fine. Only problem is I believe the grid side converter block is causing a lot of low frequency harmonics on my output current signal.
To try and eliminate this I want to replace the IBGT converter block with an approximate controlled current source and three controlled voltage sources. I need to use the three gate signals for each phase for maths operations to approximate the converter.
So my question is how can I break the gate pulse signal into 3 seperate pulses, one for each phase? I have tried demux but it isn't working for me. This is probably a real easy fix.

It's not clear what you mean by "break the gate pulse into 3 separate pulses" ?

Hello Mark,
sorry for this being too late for you. Use mux and demux blocks to access combined signals. You can also use selector blocks for this.
Regards,
Joel
