Part Number:TIDM-BIDIR-400-12
Tool/software: Code Composer Studio
Hello, again.
Thanks to your help. I can keep following the TIDM-BIDIR-400-12 reference design.
Today, I got a problem with ADC.
As I can see the tiduai7.pdf, Page 36, figure 44, I'm testing the buck mode open loop.
In figure 44, ADC for input voltage/current, output voltage/current is referred Gui_Vfbin, Gui_Vfbout, Gui_Ifb, Gui_Iout respectively.
As you see that page, it said output power is 72[W](6A,12V)
I have a question about this power. In figure 44, input power is around 182.9[W] and output power is 72[W].
I think this input current for ADC doesn't make it sense.
The figure below is my result.
In my Hardware, Power supply for input indicates 390V/0.21A, Electric Load indicates 2ohm/5.448A. So it matches input current for ADC I think.
Another question is In real hardware, 5.448A is correct, But in real time ADC indicates the double value of it. (I changed the phase, rechecked the value, it is almost the double)
I think my current to voltage circuit is the problem. In tidrhs9.pdf,
This is the before filter circuit for output current(.
If my ADC values are doubled compared with the real value, where and what can I fix the circuit? If is not the problem of my circuit, what can you recommend for my problem.
Thank you for your help.
