smps complete circuit

Hi people, I'm using Multisim and I need to simulate an entire smps circuit, to converte 230V 50Hz to 12V approximately.

Can everyone help me please?

I searched for 7 hours but I wasn't able to do that. I did a linear power suply and it was simple but this one it is beeing very difficult

Thanks

Hello Rubencoelho,

 

First you need a well understood of SMPS circuit (electronic skills) so follow this 5 video tutorials on youtube : Youtube tutorial

 

Second You need to know how it works in NI environnement (Power Electronics Design with NI Multisim) so follow this one : NI Tutorial

 

Third you need more knowledge in multisim : Multisim tutorial

 

Best regards,
