Other Parts Discussed in Thread: UCC2817A, UC2854A,

Hi:

I have a project I want use UCC28707 to design 10KW solution

vin=220VAC Vout=400V Iout=50A

Is there any suggested route or design?

Hi Joey,

Thank you for your interest in TI's products.

The datasheet goes through the designs steps to setup the controller in the power stage.

We have a 5kW reference design which would be a good starting point, http://www.ti.com/tool/pmp4311

There is also a Pspice model for the controller, www.ti.com/.../getliterature.tsp

Hi Joey,
There is a 5kW reference design available but nothing available for 10kW.
I recommend that you evaluate the 5kW design, run the calculator tool for 10kW and check the components that need to be upgraded for the extra power involved.
Hope this helps.
Regards
John

Hi John:

If i don't want XFMR_CS4200V does TI have no CT solution

because CT L/T and accuracy difficult to control.

TIDA-0130A(001)_Sch.PDFHi Joey,

You can replace the current transformers with current sensing resistors.

The attached schematic implements a 300W design with this method.
