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! Thanks for the help. However, it looks like the link that you are referring is not working anymore?

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)
