I have used the Iposim to calculate the total losses of IGBT (fz1500r33he3), but when only heatsink's parameter is changed, the total losses is also modified.
I think, when the current , switch frenquency and so on are not changed ,the total losses must be fixed. why is the total losses modified in IPOSIM？Show Less
We want to use SGB07N120 at linear area as high voltage linear drop output. Of course, the output current of high voltage LDO is very low, e.g. 5mA. Do you think SGB07N120 can work as linear area. If yes, do you have FBSOA of SGB07N120 ?
I would like to please confirm that for the FS820R08A6P2B of the HybridPack series is mounted next to the silicon chips on the DCB as described in this application note? I think yes, but the application note is from 2009, so I was hoping to please politely confirm this. (Picture from application note).
Thank you very much,

I have attached the circuit of IGBT module. I didn't apply any signal to T1 and T2 . can you tell me what is T1 and T2 in this diagram. Show Less
have well tested gate driver based on IR2110 wich is isolated by VO3120 opto isolator. H bridge has RCD clamping snubber as well. it works properly at our full load condition with out transformer at
the output. When we connect the transformer at the AC output our module getting damaged. Can you please help me
to track the issue? Show Less
I am new with IGBT (I have experience with mosfet). I need to develop a H-Bridge to drive (and test) custom magnetics (transformers/inductors).
IGBT are required because the large current I need to manage (up to 300Vrms).
I focused my attention on IGBT modules (EconoDUAL™ 3 / EconoPACK™ 3) in dual and four pack configuration. Can I have your support:
- Can you suggest me the easier (and faster) way to get a result? Am I in the right direction?
- Is there any evaluation board for IGBT driving?
- What about IGBT paralleling? In the case I would implement a modular solution?
Any suggestion is well accepted.
We used here in the company the 1ED020I12-F2 driver and IRFPG4063 in a full bridge inverter (bus voltage 400 Vdc, output 220 Vac 60 Hz).
The gate resistor are 22R, the RC in the desat pin is 470R resistor and 220pF capacitor, with a diode UF4007 in the collector of each IGBT.
The power supply is single, 15 Vdc, the miller clamp pin is connected directtly in the gate of each IGBT. The operation frequency is 20 kHz.
This solution works very well. But the 4063 IGBT is obsolete, so, our distribuitor offered the alternative of IKW50N65H5 IGBT.
With the same configuration, this IGBT doesn´t support the short circuit test. I try change the RC in the desat pin to 100R and 100pF
The peak current in IGBT during short circuit is about 140A, i believe that this value is very close of the maximum capacity of IKW50N65H5.
What can i do to use this alternative IGBT in circuit?
I was wondering how the geometric tolerance for the M8 mounting holes on your IGBT drawing in the technical specifications for the FZ1800R45HL4_S7 IHM-B module was derived?
I am trying to make an assembly with this part and the tolerance zone of 1.6 mm called out in your drawing from DATUMS A, D, and seems puzzling to me and fairly large. Could you please provide some documentation on how this tolerance in the spec drawing was derived or the reasoning behind it from the mechanical dimensions of the bolt holes. I have attached an image of what I am talking about.
