Depending on power density and application, I want to change this converter.In your properties list, you include the following:
3. Isolated in both input and output circuit.
This means a transformer requires to be used.
Transformer switchmode topologies include push-pull, half bridge, and full bridge.
Either ZVS or a ZCS are suggested for the higher power bridge topologies, but they are technically challenging.
I will give you the best advice: Search the TI website for full bridge controllers. Study some of the datasheets and app notes. Using paper and pencil, or an Excell spreadsheet, go thru all the design equations and solve all the variables and select appropriate components. Simulate a circuit or two.
And you have not even touched thermal management, EMI concerns, board layout with safety issues in mind, protections and monitoring.
I am not attempting to scare or dissuade you. But you must be aware of the significant technical challenges, and determine whether this is a project you can actually complete succesfully.
it is not isolated ...
