DSP based DC Power supply design

I would recommend looking at the TI applications pages, for the above designs I would suggest the following:

Merchant Telecom Rectifiers

1-kW, 80 Plus titanium, GaN CCM totem pole bridgeless PFC and half-bridge LLC reference design

2kW, 48V to 400V, >93% Efficiency, Isolated Bidirectional DC-DC Converter Reference Design for UPS 

You can then use the above as a starting point to find other reference designs that may be more closely related to you end goal.

Best,

Matthew
