Is there any one who has PLECS model of AC-AC converter implemented with IGBT or MOSFET modules ? Which PWM technique is used for controlling gate signals ?

Hello,

I have attached an unsupported and undocumented PLECS Standalone example of a Sparse Matrix Converter that uses IGBTs, hopefully that helps.

To open this model in PLECS Blockset, add an empty PLECS Circuit block in a Simulink model and from the File menu, choose “Import from Standalone”.

Dear Kris,

Thanks a lot for your response. I’m trying to understand how it works.

I understood that the the matrix converter converts AC-DC-AC.

I’m seeking to know direct AC-AC converter

Hi,

I’m not sure we have a direct AC-AC converter model to share unfortunately. But I’m sure if you do a web search of the technical literature there are strong resources available to you!

Regards,

Kris
