1. sinking current to ground, Lithium battery discharge (29V) ,15A current.
3.Current accuracy within 5%.
4.output:Lithium battery 29V, MAX30V
5.transistor:used MOS IRF540 before, but cannot reach 15Aã€‚
If you have a better recommendation circuit or better informationï¼ŒI would appreciate itã€‚What should I pay attention to in the design?

I am using the provided simulation models of IGOT60R070D1 to evaluate the power losses on a half-bridge LLC circuit. I run simulation on SIMetrix-SIMPLIS Elements 8.20 and LTSpice XVII but both the software get errors with the encrypted Spice model. Could you provide the non-encrypted models for the simulation?
Thank you for considering my question Show Less
I'm using this transistor as an H-bridge (class D amplifier), driven by the DRV8702Q1 from TI. The voltage supply is 30 V and the output filter is composed of a 82 µH inductor and a 68 µF capacitor.
The voltage generation is made using two PWMs generated by an FPGA, bipolar switching. The problem I have is that when I increase the output voltage to 22 V, one of the top transistor burns (gate-source resistance goes to 0). I've tried everything I could come up with, but still haven't found the problem.
All the gate driving signals seem all right. I'm using a driving strength of ~250 mA, which would seem to be ok.
Do you have any insight?

While testing the low side with a lamp which draws 3 Amps at 12V, I observe the following.
Blue - Phase - line
Yellow- Gate pulse (15V)
I am not sure why the last phase of the turn on takes so long. Am I driving it wrong or is it a characteristic of the MOSFET. Show Less
I have tried to obtain the characteristics curves of IPW65 series MOSFETs with Infineon Level 3 PSpice Libraries (with SIMetrix Tool). But, the the characteristics curves are mismatching. (Simulation done based on the references of
AN_201412_PL52_008) Show Less
I am having hard time identifying this SMD. I believe it is Mosfet, but I am not sure. The SMD is used in a Siemens VDO instrument for tachograph calibration. It says AL P61 on the package.
It would be great if someone out there knows what is the nature of this SMD. On the Internet it says it is P channel Mosfet, but it is inconsistent because other links say otherwise. As I said, this SMD is soldered in a VDO Kienzle tachograph calibration instrument and inside the instrument there are a few elements produced by Infineon and I thought that someone at Infineon might know about the nature of this SMD.

A N-Channel Mosfet when in the on-state and no drain/load current flowing, the Vds voltage would be zero (i.e differential voltage across drain and source). At this point, when a load connected to mosfet's source is switched on by an external switch would draw a 50A of DC current. How to interpret the SOA curve
at these conditions when drain/load current begins to flow and Vds (voltage Vds = 0V, i.e 48V on either side as an example)
Example mosfet: https://www.infineon.com/dgdl/Infineon-IPB017N10N5-DataSheet-v02_05-EN.pdf?fileId=5546d4624a75e5f1014ac4a981111eed
Can any one help me explaining how to interpret the SOA curve?
Thanks for the help. Show Less
Hello every one ,
I have purchased two 3Kw_2llc_c7_20 Evaluation Boards (DC-DC converter)
when I have Given rated 400VDC , one board is operating in normal mode giving 54V output But another board is not giving the output, I have tried from GUI interface both Boards are working properly I will Share you the screen shot below of GUI window
In Second Board Memory fault status register is highlighted in RED color I have shared the GUI manual in that page 8
Appendix A status register description there is a explanation about memory fault
but if have erased the MCU flash and dumped Hex file given by the Product registration information its not working
please guide me the following issue.
I want board 2 to work as normal mode like Board 1 is working .. I have source code given by Infineon for 3Kw_2llc_c7_20
and also HEX file.
Does anyone have suggestions on using the above mosfet for current sharing in a H-bridge configuration? Each switch is composed of 10 mosfets in parallel for a total current load of 600A. I am having issues with one of the mosfets overheating due to unbalanced current sharing. Does anyone have suggestions on PCB layout and long-term reliability of this approach for current sharing?
