Dear all,

I'm a college student and I need to realize some analysis in LTSpice to design a Gate Driver for the IGBT FF400R12KT4P. I couldn't find its Spice .lib model neither in the component's page nor in the Simulation Model Finder (https://www.infineon.com/simulation).  Can you please help me to get this Spice model file or any dual IGBT Spice model file?

Thank you in advance for your time and consideration. Have a nice day!

Hi ,

I am reading your application note of " InfineonApplicationNote_PFCCCMBoostConverterDesignGuide-AN-v02_00-EN: 

in that regarding inductor selection application note stated that - " In this evaluation board design, a 60 μ permeability Kool Mu core from Magnetics Inc. is used. It consists of two stacked of “Kool Mμ” 77083A7 toroids cores from Magnetics Inc., with 64 turns of 1.15 mm copper wire"

I am little bit curious about details calculation of number of turns specially for two stacked core, I did some study that says in parallel stacking of two cores inductance is doubled mean length of magnetic core is remain same  and area of cross section is double is it correct ?

Can I use following formula to calculate number of turns 

L = ((u0 * ur* N^2*A) / l)

where u0 = permeability of free space , ur = relative permeability of core material , N = Number of turns , A = cross sectional area of core and l = mean length of magnetic path 

Hi All,
 I had used the following IGBT Module in motor driver application 2years earlier. But due to some reasons, I'd stopped there.

Part Number - FS35R12W1T4 FS35R12W1T4 

Now I'm engaged in development of the same. But the IGBT that I'm looking for gone obsolete. Can anyone suggest some alternative matching the same specifications?

Thanks

Hello,

I am building a high voltage inverter operating at 200v. i am using isolated gate drivers and the supply for the gate drivers (15V) is also isolated. But the inverter switching causes a voltage spike in the gate driver power supply . the spike is happening at 40khz which is twice the switching frequency of the inverter. I have dc link capacitors and mlcc filtercaps attached to the dc line

Can someone help me figure out why the inverter switching noise is propagating to the low voltage side.

Thank you
