工程师

U2 D 和S直接之间的线宽我用的120mil, 四个S我也是用120mil 连接的， 这样对吗？

另外， C11是25V, 连接到D4，我用的20mil, 是对的吗？

期待你的回复

谢谢

IGBT will cut off the high current when shutting down, at this time there will be the overlap of current and voltage to produce large losses; alone look at the voltage and current stress are in line with the specifications under the premise of how to determine whether the loss of shutdown is within the SOA. (Assuming that the duration of the process is very short, that is, the instant of startup)

We're working on several induction systems for integrated use in tanks.

Planning to base the 230V 16A 1-phase designs on the evaluation kits provided, but we also need a 400V 16A 11kW system for use with 1-2 coils (2-4 IGBTs)

Can you please assist in the general components recommended for the EMI filter, bridge rectifier circuits and IGBTs for such a setup? 

Should we use one 400V 3-phase bridge per IGBT pair or share it? 

Suggested capacitors needed per IGBT pair?

Any pointers in the right direction is appreciated.

Dear community members

I need to measure the temperature of an FF800R12KE7 IGBT with an NTC sensor. I would like to know what is the best position to place the sensor. I tried around it but the temperature varied a lot with the position of the sensor. I plan to place it below the IGBT. But I wouldn't know which side would be better or if the ideal is right in the middle.

Kind regards,

Hydrogen production power supply front-end topology, how do IGBTs work in the DC/DC section, and why use two of them?

When simulating this topology above, Q1 and Q4 select a half-bridge IGBT, Q2 and Q3 select a half-bridge IGBT, and dual switch is selected in the circuit configuration, but there is no content inside the IGBT list, as shown below:

Do any of you know what's causing this? Or am I setting something up wrong? Thanks!

What is the power of the control signal section when this IPM, IKCM30F60GD, is operating?
