MOSFET (Si/SiC) Forum Discussions
we have SIC MOSFET with Gate driver design and refer to the IFX web EVAL_3KW_50V_PSU.
Can you help us to review the schematic and also advise good component vales? thanks!
I have a doubt in 3.3kW PFC stage in the given Infineon code for 3.3kW PFC demo board. The VIN AC RMS voltage is calculation is done by using a digital filter . The Vin sensed ADC reading is sampled at 30kHz. The digital filter function is called every 2.5kHz. The output of filter is considered as average AC voltage . This average voltage is multiplied with 1.111 to get RMS AC voltage. I want to know the cutoff frequency and type of filter used.
Below the equation used in code for filter. g_U_in is the ADC reading for Vin Ac sense.
I am going to purchase some sample of IPN80R900P7 MOSFET for our LED lighting design project. But it is unable to source it in the current market. Any alternative component can be advised?
Hi, I notice that IFX released a series of mosfets with top-side-cooling package, such as TOLT, DDPAK and QDPAK. Since the top surface should be attached on the heatsink or cool plate, I wanna know how much stress(PSI unit) the package could endure and where to find the figures? Any application note is available on the website? thanksShow Less
そこで質問ですが、SpiceモデルではDriver SourceピンとPower Sourceピンが同じピンとしてモデリングされていますが、SW損失はDriver Sourceピンが存在しないため若干悪い結果になると考えてよろしいでしょうか？
Regarding to EVAL_3K3W_TP_SIC
I'm trying to change the dead time thru below GUI.
the prolem are:
1) I have no idea what is the actual time (ns) of count unit in GUI, for example MAX 12 counts CLK what is the actaual time?
2) For reg1_limit 4,172 counts of current ADC , What is the actual current (A)?
3) Current ADC in GUI mean output current, right?
4) Diode_to_Switch, what dowws it mean?
Recently I purchased the Evaluation board EVAL_3K3W_LLC_HB_CFD7 it gives the output voltage between 43.5 volt to 59.5 volt.
Along with the board I also got the source code of the in the exclusive content.
I uploaded the same source code in the evaluation board using KIT_XMC_LINK_SEGGER_V1 debugger by following the steps
1. Import the project in the DAVE IDE
2. Generate the code
3. Build the project
4. Debug the code into microcontroller
5. Resume the debug and then stop.
Problem :- After uploading the same source code into the evaluation board the board is not giving the output voltage means it is not working as same as before but I didn't change a single line in the code.
There was a hex file also in the source code folder but which I was not able to upload in the evaluation board.
I want the board to function as same when it was procured from the Infineon there is no physical damage in the board.
Please send the following characteristics of IRF7306TRPBF.
(1)Drain current vs. Drain-source voltage -4 V or less. The following is desirable..
(2)Capacitance vs. Gate to Source Voltage. The following is desirable.
Does Infineon offer ESD ratings for their power MOSFETs? If so, where would that information be found?
I'm specifically asking about N-Channel Power MOSFETs. I would like to know in general, how to find this information for any component.
we are intreated in this 48V BSG inverter. could provide the Gerber file & related material, we would like to follow this kit to build up the prototype.
in addition, do you have a suggestion for MCU to communicate with this board? thanks.
