I am currently building Push-Pull converter 12V to 315V 600W 50kHz. I am trying to use UC3846 controller as it seems like properly designed circuit is very robust. I hope someone can help me finding PSpice model of the UC3846(or UCx846 or UCx856) chip, or even better if someone has similar simulation completed. Thank you very much in advance.
I found the model but i can not get the desired output using that model.
Is there anyone that can help with the design for UC3846.
Please, any help is appreciated.
