Part Number: UCC28950
Other Parts Discussed in Thread: TINA-TI,
Hi,
I am planning to design a 2.5kW (84V 30A) PSFB converter (offline with Vin = 390V) for a battery charging solution. I have somewhat understood the ways by which this topology achieves ZVS and the significance of Leakage/shim inductance, Mosfet Coss, and deadtime in order to achieve this.
I tried using the WEBENCH designer for this however it seems that it doesn't accept any output voltage greater than 50V. I would like to know if this is the limitation of the WEBENCH designer tool or is it that the IC is not designed for it. I don't think the latter reason might be true as the output to input transfer function is simply dependent on the max duty cycle and transformer turns ratio.
Please let me know if I have missed something or whether this IC can actually work for this solution.
Regards,
Jonathan.
P.S - I have got the required values for the above converter using the calculation sheet SLUC222D and also referring to the design application note SLUA560C. Will be proceeding with the simulation of the design on TINA-TI. I would appreciate it if someone could verify the calculations.
