IGBT Forum Discussions
Dear all,
I hope you are doing well.
I want to know how I can calculate total thermal resistance(6 diodes with 6 iGBTs , take them in parallel or series) for the IPM IGBT Module without a heatsink.
Thanks
Show LessFor the drive signal of the IGBT module, what is the recommended time required from the beginning of conduction to full saturation conduction, and from the beginning of shutdown to complete shutdown? For high-power modules, IGBTs are often three-tube packages, two-tube packages, or even independent single-tube tubes. How long is the recommended turn-on and turn-off time for this kind of drive?

The output is also three pins, and the maximum output is 150A. Why can the small pins output such a large current? Are drinks made of special materials? Also, the internal packaging line of the module also looks quite thin. I don't know why it can flow through such a large amount of current?
Show LessHi, i am using IGBT to control PMSM, for example, if the normal voltage of pmsm is 600V, the current is 300A, How to choose IGBT category according to current and voltage?
Show LessI want to make sure that the product (FF600R12ME4) purchased is genuine.
I purchased from the stock market.
The external shape and internal die shape are strange.

IGBT test questions:
- Test IGBT models: IGW30N65L5 and IGW40N65F5, Q1 and Q2 in the figure below;
- Testing tools: multimeter;
- Battery voltage is 28V, load resistance is 2Ω, and the current is about 12A after connection;
- Measurement process:
(1) Remove the positive electrode of the No. 2 battery to control power for Q1. Q1 is conductive. E1 can measure the voltage 27.2 V voltage, UC1E1 measures 0.8 V, and the measured C2 point voltage is 27.V, and there is a voltage display;
(2) When the multimeter diode level is not energized, it can be measured that both CE ends have anti-parallel diode characteristics. The red pen is C, the black pen is E, and the multimeter has no voltage display, normal; if the red pen is placed on E and the black pen is placed on C, the multimeter has a voltage display, IGW30N65L5 shows 0.502V, and IGW40N65F5 shows 1.4V.
The summary can be obtained: IGBT has an anti-parallel diode. Now I hope IGBT does not have anti-parallel diode characteristics. Or will the No. 1 battery conduct will charge battery No. 2 in reverse. I hope the manufacturer can test it and give the test results
