Thank you FvM for your quick feedback.
You are right. VDRV was huge and it has to be reduced.
However, I've seen in this article: http://www.radio-sensors.se/download/gate-driver2.pdf, that for high side gate drivers, there are the following conditions:
VDRV < VGS,max
VIN < VDRV - VGS,Miller...
Hi,
Thank you FvM for your answer and advice! I added a non-isolated totem-pole gate driver for the switch as in the figures below (with VDRV = 350V as Vin = 270V)
Unfortunately, my schematic still doesn't work properly. There is the following warning message: "The no_ramping...
Hi BradtheRad,
Thank you for your idea.
I've thus reduced the time step to 100n, because at 10n and even 50n, SABER seems to have some difficulties to find numerical solutions at the beginning of the simulation.
But a smaller time step doesn't change the problem. The...
Hello,
I would like to simulate a buck converter in closed-loop with SABER. Here is the schematic:
Classically, there are two loops with PI controllers: external voltage loop, and internal current loop. The output of the current loop's PI controller is compared to a sawtooth...
Hello,
I would like to use UCC28950 controller in SABER schematics in order to control a phase-shifted full-bridge converter.
I meet some problems to translate Pspice model into SABER model. There is a following error message:
But, I find that there are 2 news files that...
Hi mvaseem,
Thank you very much for your feedback. I used CSHUNT option with a value of 1e-13, but it hasn't converged yet.
May you send me the simulation that you modified so that I can have a test?
Thank you very much.
Sciebou.
Hello,
I have again a convergence problem with the simulation of the following circuit including C2M0080120D model:
Circuit's topology:
Error message:
I have adopted the auto-convergence option like in mvaseem's messages above. Still, the convergence problem persists...
Wonderful!
It seems that there isn't an auto-convergence option on the previous versions than 16.6.
But when I tried with the 16.6 version of Pspice.
I works perfectly.
Thank you very much for your kind help.
Hi mvaseem,
Thank you very much for your quick answer.
You are right, the picture didn't appear. But you have answered to my question. I tested the .lib file and it works perfectly with a simple circuit.
However, when I add a voltage sweep Vds rising from 0 to 18 as in the figure below:
The...
Hello mvaseem,
Many thanks for your feedback! The text file effectively works.
Otherwise, my work consists of modeling an electronic circuit with many components and so on. As I'm not used to build circuits with codes. I'm very interested to import .txt file to .lib file so that a new component...
Hello,
I start to work on modeling of SiC based converters and need to have reliable model of SiC MOSFET in Pspice. I found a CREE model of SiC MOSFETs C2M0080120D on the following website...
