- In Simulink, there is no specific block that directly provides a Delta-configured three-phase source. You need to design this configuration manually. To simulate a Delta-connected three-phase source, use three individual "AC Voltage Source" blocks and connect them in a Delta configuration. This involves connecting the positive terminal of each source to the negative terminal of the next source in a closed loop.
- For 3 phase Delta to Wye transformer, use "Three-Phase Transformer (Two Windings)" block to configure the windings. This block does not have a direct parameter to control phase shift beyond the shifts provided by the winding configurations (like Delta-Wye or Wye-Delta, which give a 30-degree shift). If you need a specific phase shift by cascading multiple transformers.

I am trying to create an 18 pulse AC to DC transformer Thyrister rectifier that starts with a Delta 3-pahse source. I am struggling to find the blocks needed to simulate it. I am looking for 1) a 3 phase Delta source block and 2) a 3 phase Delta to Wye transformer with a paramiter that controls phase shift. I also need both to have 3 taps.
I am hoping a block exists because i am new to matlab and do not know how to create a block on my own.

Creating an 18-pulse AC to DC transformer with a thyristor rectifier in Simulink involves setting up a three-phase system with specific configurations. Here's how you can find and configure the necessary blocks:
For more details look into the following documentation:
