Automotive 200-VA High Frequency Inverter Design

Other Parts Discussed in Thread: TIDA-00122

The document regarding this inverter design shows several inconsistencies (not matching ref designators, missing components from schematics or BOM, components of Gerbers that do not show in schematics, schematic titles, etc).  I guess that there were different revisions without updating some of the docs.  These inconsistencies refer to:

a) The schematics shown in SLVA578.pdf dated March 2013

b) The BOM shown in SLVA578.pdf dated March 2013

c) The published BOM called PMP3715REVC_BOM.xlsx

d) The published Gerber files called PMP3715RevC_Gerber

All the above files are accessible from "ti.com/tool/TIDA-00122".  A couple of questions to the forum:

1) Did anybody build this inverter to validate the design?

2) Can someone identify which documents are valid or what the errors are?  My first inclination was to believe the last dated doc (the application report) but it itself has inconsistencies between its own BOM and schematics.

3) Are the native design files for schematics and PCB (probably Orcad/Allegro, any version), still available anywhere?

Thanks...!

    Well, this application is apparently not related to the MSP430 MCUs (and 200VA isn't really low-power), so the MSP430 ultra-low-power microcontroller forum surely isn't the right place for this question. But perhaps a moderator can move the thread to a more appropriate place.

    Edit: Okay, it is an MSP430 related design, as the H-Bridge is driven by an MSP430G2330.
    However, as it is an Automotive application, I'd say that the Automotive forum is a better place.
