Hello,
I am designing a EV battery charger with the following specs. I have decided to go with Half bridge LLC topology for DC-DC converter
Vin= 400Vdc
Vout=(40-60) vdc
Iout=35A
Maximum power=2000W
I would like to know whether we can use UCC256403 with a gate driver for above application!!
Please suggest any other LLC resonant controller from TI in-case the above controller is not suitable.
Regards,
Biswajit
Hello,
The UCC256403 controller itself does not dominate the power level it can be used for. The FETs you are driving do have more of an influence based on gate charge, miller plateau and gate drive current and thermals.
There is a training presentation at the following link on designing multi kW power supplies that you may find helpful in doing your design and selecting the correct power supply controller. training.ti.com/designing-multi-kw-power-supply-systems KW REFRENCE DESIGN&tisearch=Search-EN-everything
We also have many reference designs to use from to help in the design process. The following link will get you to a 1 kW design using the UCD7138/UCD3138A
