UCC28950 BI-Directional Use

Other Parts Discussed in Thread: UCC28950

Hello,

My company recently started developing a Bi-Directional DC-DC converter to go from 14 to 400 VDC and vice versa. We have settled on using a full bridge topology and we were wondering if the UCC28950 would support this?

We also ran across an evaluation board from Infineon (EASYKIT DCDC) that uses this chip for the controller and it left these notes for reverse power flow. 

*the power stage is suitable for reverse energy transfer but the control can cause wrong PWM patterns,
which can lead to failure of sync rectifier MOSFETs as well as the HighSpeed IGBT Module.

I am assuming this means the chip will probably not support this function.

If not, would the TI kit HVPSFBKIT support this ability with some modification?

Thanks!

    The UCC28950 can be designed for a system that requires bi directional power flow (also called two quadrant control).

    You can find a TI paper written on this subject here

    Also there is a TI reference design based on the UCC28950 that employs bi directional power flow
