  hello! i am simulating a high power transformer in maxwell and i have to give a square wave with 50% duty cycle as an input to the coil terminals. I would really appreciate it if you could write it in the exact words as i am supposed to write it in maxwell. The frequency is 20khz.

  Hi @iamhsafi you can use a pwl function to define the square voltage.
  You can look at the following forum discussion for how to define a pwl function. Change units appropriatly
  /forum/discussion/comment/116644#Comment_116644
  Please refer to Maxwell help document for more detail on defining pwl functions.

  Hello,
  Method 1 insert a dataset and use pwl(datasetname, time)
  Method 2 use sgn(sin(2*pi*time*Freq))
  Method 3 use external circuit and pulse source

  Hi,
  Correction Method 2 use 0.5*(sgn(sin(2*pi*time*Freq))+1)
