TIDM-02000: Q5 & Q6 turn on at the same time? (boost mode)

Hi Jiang,

One more question.  In that paper, I found the gain almost at the transformer, is it correct? 

The two transformers P6524_A and AF5551R are 12:1 ratio. However, the problem is the voltage ratio is too low to achieve 12V transforming to  400V in the reference" TIDM-02000" or "TIDM BIDIR-400-12". 

ex: 12*1.05=12.6V, 12.6V *12 = 151.6V

What do you think?  Please let me know, thanks.

Hi Jiang,

Is there any update about the gain problem of the boost mode?  Please let me know, that is important to me.

Thanks a lot!

Hi Sway,

You can combine equation (6) and (7) in the paper to get the relationship between Vin, N and Vo(referring to figure 1).

Thanks a lot!
