Exponential Vsine Source

      Hi to everyone. 

      Im working with Ansys Maxwell.

      I need to parameterize a Vsine Source with an exponential signal for the first cicles (as show in the image below)

      (I have to parameterize this signal in Maxwell Circuit Editor) 

      I have tryied to parameterize the Vsine sourse with the next fuction on "Vpeak",

      (1-exp(-50*TIME))*(13800/sqrt(3))*(sqrt(2))

      but, I havent obtained the correct signal.

      Does anyone how I have to parameterize (correct) this signal

      This is the correct signal

      Hello @azaelmartinez84,

      The expression looks correct to me. Could you show the incorrect waveform you are getting?

      Thanks,

        Hey GLUO! Thanks for your support. 

        Well, that´s the waveform that I´ve obtained. It is very different.

      Hi @azaelmartinez84,

      I just remember the variables in external circuit are only evaluated at the first time step. Your expression can be directly used for internal sources.

      To realize this waveform in external circuit, there are two methods.

      Method 1:  Use two VSin sources connect in series, both with (13800/sqrt(3))*(sqrt(2)) as amplitude (Va). The polarity of the second one is switched and Df =60. Please refer to the guide below.

       

      Method 2:

      Simply use VPWL instead of VSin. You could define your waveform as a dataset and import it.

      Regards,

      GLUO
