UCC28950: full bridge converter. secondary side control

Part Number: UCC28950
Other Parts Discussed in Thread: UCC28250

Hi, I want to design 3kW rectifier. I would like to design a dc/dc converter as a full bridge converter (no phase shift)  and do secondary side control.

I am trying to use UCC28950, is it possible to operate full bridge? 

If possible, please tell me how.

Is there any other recommended ic other than UCC28950?

Regards,

Kwangwoon

    Hello,

    The UCC28950 uses phase shifted full bridge to control the duty cycle.  It can be designed for 3 kW and has zero voltage switching. 

    If you don't want to use phase shift control you could consider using the UCC28250.  This device was designed for half bridge converters and full bridge converters. 

    Regards,
