Phase shift full bridge

Thread Summary

The user inquired about a PSFB controller solution for a 2kW step-up converter (48Vdc to 600Vdc) with bidirectional support. The support engineer confirmed that the selected controllers (LTC1922, LTC3722, ADP1046A + microcontroller) are not designed for bidirectional operation. The engineer suggested the non-isolated bidirectional LTC7871 demo board (DC2886A) and the LTC3871 demo design (DC2348) as potential solutions, which could be extended to 6 phases.

Hi,

I am looking at PSFB controller solution for 2KW (48Vdc to 600Vdc, step-up).

If there is a solution with bidirectional support I am happy (or) I need boost implementation.

Input voltage: 48Vdc

Output voltage: 600Vdc

Output power: 2KW

Some of the controllers selected and not sure whether it can be used for the above specification or not.

Selected controllers

LTC1922

LTC3722

ADP1046A + microcontroller

Please suggest if any other better part will meet the requirement.

Thanks,

Sakthivishnu
