Hi,

Please see PMP8740. This is the closest reference design that I could find to your requirements. This is a phase-shifted full bridge providing a 2kW output adjustable from 0-32V output. For your requirements, the phase-shifted full bridge would need to be adjusted to accommodate 120V output.

best regards,

Brian

Hi Brian,

Thanks your support.

This PMP8740 is based on microcontroller.

Is there any chance to do design with like UCC28950 etc.,?

Hi Brian,

Thanks your support.

Can i use UCC28950 to generate 0-120VDC?

Hi ,

The PMP8740 design does use the UCC28951 to control the power stage. Yes, it is possible to use the UCC2895x devices to generate 0-120V output. The PMP8740 design can be used as a starting point, but obviously, the power stage would need to be redesigned for the higher secondary voltage.

best regards,

Brian
