Dear Sir,

we have SIC MOSFET with Gate driver design and refer to the IFX web EVAL_3KW_50V_PSU.

Can you help us to review the schematic and also advise good component vales? thanks!

 

kind regards,

 

Kuo

Hi Kuo,

I have reviewed your Schematic. You can consider following components

Sic MOSFET - IMZA65R048M1H

Gate driver for Sic MOSFET   -  1EDB9275FXUMA1 

Gate resistance – 10 ohms or lesser. ( Using higher resistance like 100ohms will increase turn ON and turn OFF time which will increase the switching loss)

Please refer following documents for better design understanding.

Application notes:

You can contact us for further support.
