TIDA-00366: working temperature of Power module?

Part Number: TIDA-00366
Other Parts Discussed in Thread: TIDA-01420, TLV521

hi every one

I want to set the temperature of my IPM.so would you please tell me the maximum  standard temperature of IPM ?

in most VFD's they consider heatsink temperature around 60~70 C ,is that different from IPM temperature ?

thanks

Dave. 

  • Hello Dave,

    thank you for your interest in the TIDA-00366 reference design.

    TI does neither offer IPMs (integrated IGBT power modules) nor IGBT modules. Therefore I cannot tell you the maximum heat sink temperature for your IPM or IGBT module.

    Please check with the vendor of your IPM or IGBT module what the maximum recommended temperature for your IGBT power module is. Please consider that the heatsink temperature is not equal to the IGBT module's junction temperature.  The vendor of your IGBT module may help you here too.  

    Regards,

    what I meant was TI Designs: TIDA-01420,

    Basic Isolated Three-Phase Compact Power Stage Ref Design for Industrial Drives (ti.com)

    take a look at page 9

    2.3.1 DC to Three-Phase AC Inverter Subsystem

    In this reference design, IGBT module CM100TX-24S is used to characterize the UCC5350MCD. The CM100TX-24S is a 1200-V, 100-A IGBT module that has an internal gate resistance of 0 Ω

    please take a look at it.

    this IGBT module  NTC  resistor need  to be set at a certain temperature in order to have fault in over heat IGBT module, how much should be set it in our program? 

    thanks for attention

    Dave.

  • Dave,

    thank you for clarification. The IGBT module used with TIDA-01420 is also not from Texas Instruments, but Mitsubishi. I cannot comment on the maximum recommended operating temperature of this IGBT module and related heatsink temperature. I'd like to refer to the corresponding date sheet of the CM100TX-24S and check with Mitsubishi.

    If you have a question on the signal chain design to sense the temperature of the NTC, which use Texas Instruments products like an amplifier TLV521 and an isolated modulator AMC1306 to convert the voltage drop across the NTC to digital, I can help or course.
