TIDA-01604: Piccolo F280049 controlCARD, TIDA-01605, TIDA-01604

Part Number: TIDA-01604
Other Parts Discussed in Thread: C2000WARE, TIDA-01605, UCC21530

hello, i have a question.

I am currently experimenting with 3kW output with the TIDA-01604 board.
There is one problem.
I've been watching the output for about 30 minutes and after about 20 minutes the output drops from 400V to 300V.
We have experimented with several loads, but after about 20 minutes the output drops to around 100V.
Is the output coded to drop after 20 minutes on the CCS code?

  • Hi Jaeyup,

    Did you download the software from the latest C2000Ware_DigitalPower_SDK? and did you follow the testing procedure outlined from design guide?

  • Which build level are you at ?

  • As this will be a board you built from the design files provided by TI , please make sure you follow the incremental build process to bring the board safely up.  

  • Thank you for answer.
    Currently I am trying to load 3.3kW using TIDA-01604.
    The device values ​​used are as follows.
    -------------------------------------------------- ----------------------------------------------------------------------------------------------------------------------------
    Inductor: 280uH
     DC Link Cap: 400uF
    High Frequency SIC MOSFETs and Gate Drivers eliminated the switching elements and gate drivers that correspond to PFC 3H.
    -------------------------------------------------- ----------------------------------------------------------------------------------------------------------------------------

    The values ​​in Main.cfg have been changed as follows.
    INCR_BUILD: 3.Closed Voltage & Current Loop
    Phase Shedding: Disabled or Enabled
    Power Rated: 3300W
    Input VL-L (Vrms): 220 (Korea's AC voltage is 220VAC)
    Inductor (Li): 0.28mH
    Output Cap (Co): 500uF
    -------------------------------------------------- ----------------------------------------------------------------------------------------------------------------------------
    After exactly 20 minutes, the output voltage drops from 400V to 300V.

  • YOu can check EPWM1Regs.TZFLG in the watch window and see if a trip has happened?

    What is the PFC current look like?

    When the PFC works do you see good PFC action ? How is the zero crossing spike etc?

    Have you checked the thermals? and have a fan connected?

  • Thank you for your answer.
    I'll check what you said.
    Let me ask you a question about the gate driver.
    You can see the TIDA-01605 schematic as shown below.

    Currently I am using UCC21530. As mentioned above, I removed R30 & R32 and soldered R31, but the high signal did not go to the enable pin. I confirmed it. Please make sure I am right.

  • Hi jaeyup,

    what is the signal at OUTA and INA of U7 during normal operation? Can you confirm?

  • Hi Xun,

    Currently, I am using the gate driver UCC21530. Soldering was followed by soldering 5.1k ohms to R30 and R32, with the exception of R31. As a result, a PWM waveform is coming out of the gate driver.

    Is Xun telling me to check the waveforms of U7's INA and OUTA in my current circuit?
    If it is correct, the whole circuit is not operated, and the PWM waveform is coming out from the gate driver.

    Is Xun telling me to check the waveforms of U7's INA and OUTA in my current circuit?
    If yes, can I check the voltage by applying 5V only to the auxiliary auxiliary power source without operating the entire circuit?

    The ACS716 shown here is different from the ACS716 in the schematic diagram of the TIDA-01604.
    I want to know exactly what the values of Re, Rf, Rfltr and Cfltr are in the schematic of TIDA-01604. Look at the schematic and tell us the part number.

  • Hi, Here is the corresponding schematic snapshot where you could correlates.
