When IGBT is turned on, many waveforms will have the gate pulled down. This is why蓝色为驱动 blue is the driver

The FF500R17KE4 device is planned to be used. The dead time of the device needs to be calculated, but there is no switching time curve in the sample. Please provide the recommended dead time for system applications and the switching time curve.

It is planned to be used in LLC circuits. The current during switching is small, about 20A, and the bus voltage is 1100V.

1. Input voltage 380V AC, output 700V, power 50KW, two tubes connected in parallel, switching frequency 36kHz, air cooling; 2. How to calculate tube loss to select the corresponding Infineon tube; 3. To verify whether the calculation is correct, IPOSIM simulation verifies whether the loss is consistent with the calculated loss; 4. The project is in the pre-research and selection stage; please help and support, thank you!

I bought two devices, IM818-SCC and IM818-LCC. Their current values don't work. How can I tell the difference when soldering to the board? The screen printing completely blocked the board. Can I measure the IGBT body diode scc 0.510V LCC0.471V as a basis?

The TLE8366EV50XUMA1 we ordered, but the actual delivery label is TLE8366EV50. According to the information on the official website, XUMA1 has a specific meaning, but currently the Material Content Sheet on the official website is MA#: MA003502968, and the actual product label also shows this MA #，这个MA #我看都符合XUMA1所标识的要求呀, so I'm not sure about TLE8366EV50 and What's the difference between TLE8366EV50XUMA1? Which model do we take as the basis for the actual order?
