STDES-DABBIDIR: A2H6M12W3-F datasheet and Frenetic transformer 32011-04 specification

We are studying the STDES-DABBIDIR 25 kW bidirectional DAB reference design (UM3198 Rev 2, TN1435, schematic and BOM v2.0) for a 30 kW EV charger power module. Two items in the documentation are not publicly available:

1. A2H6M12W3-F: UM3198 uses two of these ACEPACK 2 half-bridge modules on the low-voltage side, but st.com has no product page or datasheet for this part. Has it been released? If not, what is the recommended production equivalent?

2. Frenetic transformer, design reference 32011-04 (turns ratio 1.78, five stacked E80/38/20 cores), and the 28.6 uH auxiliary inductor: can ST share a specification or drawing, or should we request these directly from Frenetic?

Thank you for any pointers.

Welcome ​@TJafari, to the community!

I must point out that all tools whose designation begins with STDES- are design studies that cannot be purchased either. These tools may contain devices that, as in the case of the A2H6M12W3-F, are for example still in the design phase.

If any support is available at all for STDES-DABBIDIR, it is only very selectively provided, and ususally an NDA is also required; your local ST contact or local distributor can help with that.

I’m very sorry if that is a little confusing, but I hope I’ve been able to help you a bit.
