mOhm rating of SiC
It is very difficult to directly link the mohm rating to Ic rating in the application. Because Ic rating is coming from only conduction loss, there is no switching loss involved. If an application is switching loss dominating, then using the sic mosfet could give more current.

IRPS5401 won't start / initial bring-up
Hi to all,
same problem here!
We have a carrier board for an UltraZED with two IRPS5401 and they won't to ramp up output voltages. We set them with the DESIGN WIZARD of IR PowIRCenter (build 6834) without any success.
Your help is very much appreciated.

XMC4000 Background Request Source Behavior
Hello,
I posted a similar question a while ago but got no replies :( So I will ask it a bit differently :)
I have a Application where I need Results from multiple ADC Channels but have no stringent timing requirements.
Therefore I thought that the Global Background source on continuous mode would be the right choice and I would just grab a result when I need one.
This kind of works but I have some problems that may be due to lack of understanding what actually goes on behind the scenes.
I use FIFOs on some of the channels to aid with DRM/DMM, so I need Wait-for-Read Mode (It seems that if WFR is turned off on the input stage, then all the intermediate results of the DRM will be propagated through the FIFO - is this correct?)
The problem here is that if a channel with WFR set is not serviced (=read) then the background source stalls.
This is not desirable for my application since the lowest read frequency will determine the update frequency for all channels.
Is there any way around this, maybe through the use of a different queuing scheme?
Regards,
Funky Luke

Soft Reset vs Hard Reset
Hello,
I'm using TC277 controller. What are the significant differences are between Hard reset and Soft reset?
What will happen to the contents of DSPR memory immediately after each type of reset?
Thanks!

Errors in Ifx_InterfaceConst.c
Hi Dastan,
I see you're using BIFACES and also an external IDE. If you're a beginner I would suggest you take one step back, and try the following instead:
- Close your foreign IDE
- Launch the HighTec IDE instead
- Select File > New > Example
- Click HighTec Examples
- Click Next
- Expand the TriCore Free Entry Toolchain example tree
- Expand Time Demo tree
- Select the TC297 application kit (presuming this is your target)
- Click Finish
Note that if you have the latest FETC (released 2-3 weeks ago) the help menu of IDE includes a Content Manager that allows you to search our online example repository as well. This repository is updated regularly and also includes multicore examples for most targets. Each example comes with a detailed readme as well.
Note that your snapshot shows a license error. This one may still persist in the HighTec IDE. In that case you need to take a closer look at that as well by inspecting license.lic and check if for some reason it is expired.

Addressing PDO with different size. APPL_InputMapping & APPL_OutputMapping
This way of adding padding entries is a waste of memory and would also not work, you've just decremetn the padding after each entry:
BOOL (SI1)
15bit padding
BOOL (SI3)
14bit padding
BOOL (SI5)
13bit padding
....
You don't need to add padding entries if the structures does not have any implicit padding (as mentioned before the easiest way to check that is set all entries to 1 and check the memory).
If that is the case change the you could deal with the 8Bit objects, either by adapting the pointer type in in the mapping functions or by adding 1 additional 8bit padding after the last entry.

SiC in eBus auxiliary drives
Hi Nick,
by using SiC Mosfets in eBus auxiliary drives you can provide silent operation without big penalty on losses. A drive based on silicon devices targeting the same noise level needs bigger output filter and bigger heatsink. Weight saving on these parts together with the increased efficiency of the drive will make the complete bus more efficient.

Double pulse testing vs IGBTs
Hi Walter,
yes, in general I agree to the statement above. But you should consider the higher switching speed and doublecheck, if performance of current and voltage probes is still sufficient to show the true signals. Furthermore parasitic capacitances within the setup have a larger impact.

Body Diode
Hi Melli,
for thermal design you should consider that this body is only conduction during deadtime. Hence the high forward voltage is no big issue. In a typical halfbridge configuration with standard gate signals, the will be conduction of the channel most of the time (synchronous rectification).

CoolMOS vs CoolSiC
Hi Gyro Gearloose,
one main difference is the voltage range, where such devices are available. The main domain of CoolMOS is 650 V, with some parts up to 950 V. Contrary CoolSiC Mosfet can be designed also for much higher voltages.
The lower Qrr of CoolSiC Mosfet makes the suitable for halfbridge applications with hard switching, whereas the main domain of CoolMOS are single switch applications like PFC or soft-switched converters.

dv/dt for an SiC MOSFET
Hi Max Power, hi Fränce,
dV/dt of SiC Mosfets can be quite high, up to 100 kV/us, for our CoolSiC Mosfet dV/dt can be controlled quite well via the gate resistor.
Compared to IGBTs with Si FWD there is a benefit that there is no steep increase in dV/dt when turning on low currents
dV/dt at turn-off increases with drain current as the current has to charge the output capacitance
In regard to EMI you have to distinguish between dV/dt related noise (usually conducted EMI) and diode recovery related (di/dt of reverse recovery current) noise (usually radiated EMI)
The first will be worse compared to IGBTs, if higher dV/dt is adjusted, the later is expected to improve as the CoolSiC body diode has much better recovery behaviour than a silicon diode.
It is worthwhile to note that you can have benefits in losses, even if you do not adjust higher dV/dt as for IGBTs.
Best regards,
electricuwe

How to Read/Write FLASH and EEPROM of (Infineon Tricore 1782)
Reading the EEPROM is a matter of placing it in a suitable device programmer, it is just a serial EEPROM.
Reading the FLASH is a different matter entirely, if the manufacturer did not disable reading of flash it may be possible to do it using a modified CANLoader via the CAN BOOT mode.
See application note #32136
Good luck finding the code listed in chapter 7.
