Go to MATLAB simulink. Then click on library browser. In the search bar type " transformers"

It will be names as ' three phase transformer 12 terminals'

OR

Double click on the simulink work space and type 'three phase transformer 12 terminals'

Hope that helps.

Since others have already described how to do this in MATLAB-Simulink, I want to let you know about a much faster way to simulate. Use PLECS instead. You can do the same simulation and even model cross-coupling between both transmitters and receivers with n number of coils in PLECS, and the simulation time would be much faster than in MATLAB. Moreover, you can integrate the MATLAB design with PLECS if you need to use Simulink for some specific control.
