TLP251 Photocoupler Heating Up When Driving IGBT With PWM—What Could Be Wrong?

Hello Respected Seniors
I want to drive igbt with help of TLP251 photocoupler, when I apply PWM to photocoupler it starts getting heated in a very short period of time how can I fix the problem?
below is the attached file of circuit diagram

What voltages are you applying around the device?  There is a very good application note here Vishay app note which is well worth reading.Cheers,Richard

Voltage applied is 15 V

Hi Ishfaq-Just to be clear- it's the TLP251 driver that is overheating and not the IGBT, right?  It's not uncommon for the IGBT to get warm, but it is a bit odd that the driver is heating up.I would remove  Vcc from the TLP251 and remove power from the IGBT and apply PWM to the TLP251 and make sure the overheating disappears.Next,  reconnect Vcc but remove power from the load that the IGBT is driving.  Is the heating gone?  Some other information that might help us: What voltage is Vcc?  Is Vcc isolated from the logic power supply? What frequency is the PWM? Are you sure the rise and fall times of the PWM are fast?  What is the part number of the IGBT?  What is the load being driven by the IGBT?  Do you have a low value resistor between the driver and the gate of the IGBT?  This can help eliminate oscillations.You might also try a different driver, like the FOD3184, which can deliver 10X more current to the IGBT.-Rick 

Thank you, sir RICK Curl,Vcc = 15 v. yes VCC is isolated from logic power. PWM frequency is 2.3Khz rise and fall time is 8.3 nanoseconds. the part Number of IGBT i am using is G60N90 DG3113. the problem was that I was applying negative to the gate and positive to emitter which results in heating of TLP251 not igbt. when i apply positive to gate and negative to emitter now my TLP251 is not getting heated. sir, I have some problem with my circuit can I have your email address?

Hi Ishfaq-I'll help any way I can, but as much as possible please keep your comments public because the process of solving the problem may be helpful to others.If you've got something you need to share with me that is proprietary, you can go to the "Forums & Community" tab at the top of the page, choose "Experts", and under my info you'll find "contact".  Make sure to include your email if you need a confidential response.-Rick  

Thank you, sir for your kind response I have sent you message kindly check
