Good afternoon, would it be possible to replace the IGBT module 2mbi450vh-120-51 with the model ff450r12kt4, for use in a powerflex 753 frequency inverter?

Hi all,

I have a induction motor that I am trying to control using the EVAL-M3-IM564 driver board and the EVAL-M3-302F controller board.

I used the MCEWizard to enter all the parameters and generated a .txt file for the MCEDesigner. In the designer I uploaded the .txt file to the controller and tried starting the motor.

Everything goes fine until my RPM reach the "Minimum running speed" RPM value. Then it either stops or runs at 1-10 RPM depending if the previous value was rather small or big. Even if I set the "Minimum running speed" higher than the "Reference speed" parameter in the designer, the motor will keep speeding up beyond the "Reference speed" and shut down when it reaches the "Minimum running speed".

Any idea's what might cause the problem?

PS. I'll add the .mc2 file.

I am working on a wireless charger for electric vehicles and need MOSFET modules for generating the high-frequency AC. The FF3MR20KM1H might fit our application, but I didn't see the forward bias safe operating area plot. 

We'd need to handle about 560A with a pulse width of 10.6uS. 

Can this module handle this?

Hi.

hiring out

I have built the peripheral circuit of IPM module IGCM04G60HA to control DC310V,2A 3-phase motor, please help me to see where to change.

Looking forward to your replies.

thanks

1 &3. This development board has been discontinued due to design issues and is no longer available for sale, and we do not recommend any further reference to its related design, please understand.

2. Q4 is a PMOS, which serves as an anti-reverse connection protection circuit. Its gate is connected to a resistor to ground, and if a forward voltage is connected to the input, current flows through the body diode of the PMOS to the load side. If the forward voltage exceeds the voltage threshold of the PMOS, the channel conducts. This reduces the drain-source voltage ( _VDS ) of the PMOS, which reduces power consumption. A voltage regulator, BZV55-C13, is typically connected between the gate and source to prevent an overvoltage condition at the gate-source voltage ( _VGS ) and also to protect the PMOS from breakdown during input power fluctuations.

This board was released in '12, and now that the technology iteration of power supply design solutions is so rapid, it makes little sense to continue to reference a faulty board.

Hello! We performed ltspice double pulse test simulations on Infineon's three IGBT chips (models IKW75N65EL5_L1, IKZA75N65RH5_L1, and IKZA75N65RH5_L1, respectively). We found that during the IGBT switching process, the waveform in Figure 2 shows that the gate voltage suddenly drops after the Miller platform. The gate voltage waveform of some chips even reached negative pressure during this drop. At the same time, the experimental and simulation waveforms can also correspond to the simulation waveforms. I don't know if this kind of waveform is normal, I'd like you to explain it.

Hello, what are the pins on top of the IGBT module in figure 1 below? Is there any correspondence between these terminals and the endpoints in figure 2?

What is an alternative chip or solution to use IR25750LTRPBF (discontinued) to detect conduction voltage drop

The bus voltage is 400V, and the withstand voltage is about 600

Hello. - Hi! May I ask

1. Annex page 30, formula 2, when calculating the gate peak current, the denominator in the Rgext and RDriver, respectively, specifically refers to which resistors in Figure 37?

2. Why is the formula different from the one given in Infineon's article IGBT drive current and drive power calculation - Zhihu (zhihu.com)?

I'm looking forward to hearing from you.
