Part Number: TMS320F28379D
Other Parts Discussed in Thread: TMS320F28035, TIDM-1007, C2000WARE

Is there any eval kit or design guide for ac-dc converter using Delfino? No amount of wordsmithing produced any results. If there is none, how much of the code developed for the following MCU could be ported to Delfino?

  • Full digital control of bridgeless PFC power converter
  • 95 VAC to 265 VAC input voltage range
  • 400 VDC bus output operating up to 300 W
  • Full load efficiency greater than 93% and power factor of 0.98 at 50% or greater load
  • C2000™ Piccolo™ TMS320F28035 MCU is the digital controller, operating the bridgeless PFC power converter at a PWM frequency of 200 KHz
  • Fully-functional evaluation board includes software, hardware design files, quick start graphical interface and step-by-step documentation

Of course, we would like to use Delfino based code for such a converter if one was developed.

Thnx

    No, we don't have Delfino based AC/DC design at this time. You have to take that code in F28035 and port it to Delfino.

    A lot of this code you can use in your Delfino s/w except that you have to change the code involving F28035 registers to those for Delfino. The code that does not involve device registers can be used as is.

    Instead of using Delfino, I would also suggest you use our latest F28004x based AC/DC design. We have a totem-pole BL PFC example TIDM-1007 at ti.com

    The code is available in C2000Ware.

    Shamim:

    Thanks for pointing out the other device. We will use it on similar products...

    Our dilemma is that we will need 2 converters ( one PFC the other LLC) very soon in the same enclosure without much room for 2 separate MCUS.

    We chose dual core to fit in the available area.  Core 1 does the PFC functions( no current shaping required- simple voltage mode feedback), core 2 does the LLC- using TI design almost 99%, small code change for output voltage & current).

    From our previous posts, I got the idea that it would be possible to do so.

    Would you not think so as well?

    Hence for this  small departure from the main project, we are trying to keep focused on 1 MCU.

    I think we ought to be able to reuse the reference design with x4 MCU.

    Let me explore further & let you know to what extent that will be successful.

    thnx again.
