Need a suitable EVM board

Hi there,

 

I have been back to high power design.

My system contains 3phase, 380V, 50Hz  ac input, secondary surge protector, Aux Tr ( single phase, 380V/220V, 300VA), phase transformer( 3ph, 380v/12v,0v,12v,100VA) and a main transformer ( 3ph, 380V/9V,18V,800VA),

SCR(1600V, 50A) bridge, DC reactor( DC 20V,20A). Rectifier output should be DC 20V 20A.

 

My requested EVM should be,

 

1. PTR secondary windings  phase, amplitude and rating controller.

2. MTRs secondary fuse (690V, 32 A)  sensing 

3. SCRs switching controller.

4. 50mlV, 30A shunt sensing,

5. GPS communication,

6. RSM 

7. LAN

8. Display....etc,

 

 

Kindly recommend me one.

You can also transfer this post to suitable forum.

  • Hello Hasan, 

    This is the same question you asked last week: https://e2e.ti.com/support/power_management/isolated_controllers/f/188/t/694811  , and were informed that we do not have such a power supply design.  I recommend you break this design down into separate blocks, beginning with the 380VAC input, and you can look at some reference designs such as  http://www.ti.com/tool/PMP10416  . Then, use the Power reference designs: http://www.ti.com/power-management/reference-designs.html , and/or Webench to design the remaining blocks of the power sub-system. 

    What I am not clear on is your reference to RSM, LAN and GPS, so it seems this is more than just a power supply design.  I suggest you put together a block diagram of the system, then investigate each block/subsystem independently.  

    You could also consider contacting one of our third-party design services: http://www.ti.com/devnet/docs/catalog/searchcatalog.tsp .

  • Dear Sir Leonard,

     

    Thank you very much to respond in this post. Sorry for post it in other place.

    I was too busy on other work.

    Your refrence design looks cool, but I need more  well controled design.

    This power system is connected with a test station locally and also far away. System should be perform  with LAN facility ( may be for data network). Display should be use for voltage, current, time, setting etc.

     

    Last iteam, I did wrong. It should be RMCS. This system should be monitored from thousand miles away. Remot control monitoring  service is required. 

     

    For seek of simplicity, let me add a control diagram which in case should be modify in detail. This is older one.


     

     

    At this inital stage, I am afraid about data protocol. But what I have understand this I/O board should be follow RS-232 with PC.

    Design need to be more smart. Keep in touch.

     

  • Hello Hasan, 

      Thank you for the additional information in the block diagram.  As previously stated, since TI does not have an eval or Ref Design for your requirements, you will have to do some additional research for each of the main functions.  For example, the MCU might be an MSP430, and there are a number of Ref Designs with that uC.   Also curious about the remote monitor - you mentioned LAN, so would this be hard-wired cable, or would you use a wireless network?  Either way, there are Ref Designs for either method.

    Since you stated the block diagram is for an older design, wondering if you are upgrading the design and/or replacing all the existing installations, and how many of these would you build in full production?

  • As previously stated, since TI does not have an eval or Ref Design for your requirements, you will have to do some additional research for each of the main functions


    Yes, I do agree with you. At this moment I am thinking a zero crossing detection circuit for synchonization. Actually the diagram I have posted is main the concept. Later on  I will try for a firing angle control circuit and gate driver. Lets adapt this 2 function in a TI MCU or DSP. I think I need to use few MCU for this design.

    Take a look the classification, dont you agree with this diagram?


    For example, the MCU might be an MSP430, and there are a number of Ref Designs with that uC

    Dont you agree with this application, lets find more suitable one for SCR.


     

     would you use a wireless network? 

    Not sure, may be ethernet.

     

    how many of these would you build in full production? 


    It depends  on how perfectly we can develope this design.

     

     

  • Hi Hasan,

    I am bringing in a High-Power expert to give direction on this portion of the design.  Once that is resolved, we can shift to other portions of the design.

  • Hello,

    Did you find someone ?

  • Hi Hasan,

    I read through the E2E thread, and it is unclear to me the power supply requirements that you are looking for. Can you please advise:

    Input Voltage
    Output Voltage
    Isolation Requirement
    Load Current
    Efficiency Targets

    Thanks,
    Ryan

  • Input Voltage- 3phase, 380V, 50Hz


    Output Voltage- DC 20V


    Isolation Requirement-YES


    Load Current- 20A dc (depending on your load)


    Efficiency Targets   72% to 77% at 100% full load.

     

  • Unfortunately I do not have a high power design with a 380VAC 3phase input. The closest design I have is PMP11064, which is a single phase input, 20V/20A output power supply. This design includes a PFC circuit followed by an LLC isolated DC/DC.

    Unclear if your system will require PFC with 3phase input. If it does not, you can rectify the three phases and run the isolated DC/DC from there.

    Thanks,
    Ryan
