Hi all,
I am trying to run AC sweep for LLC converter but it is not recognizing the system period. Is there any way to go about it?
Hello,
For converters with variable-frequency control a Multitone Analysis should be used for generating the frequency response. The AC Sweep tool employs the Steady-State Analysis that needs the information of the system period, which for variable-frequency controlled converters, is not known prior to the simulation. Please also see the PLECS demo model “Half-Bridge LLC Converter with Analysis Tools” for an example. Good luck!
Regards,
Kris
