Dear Professor Yaakov, thank you very much for this demonstration. I really appreciate this video as no single lecture I attended explained how to embed third party part models into ltspice simulations.
Hello, can you please describe how you plot I vs V(CE) in 15:55? It looks like a dc sweep but CE isn't a source, so LTSpice throws an error. I've tried with a voltage dependent source but it didn't work as well. In addition, it looks like there is no .dc command in your schematic so I'm pretty confused. Thank you professor!
Hello Professor, thanks a lot again! in 21:30 you said it is the reverse conduction of mosfet. But why is the diode not conducting? Is the diode not included in this MOSFET model? regards!
@@sambenyaakovwell, running your embedded C/C++ code or VERILOG code for controllers is more than interesting. Not to mention that it is free. But somehow it feels incomplete, especially the user interface which is clearly lacking.
@@sambenyaakov there is ONE major advantage: You can embed C++ or verilog in the simulation , so there can be some digital filter at some point or some SW PID . Might not be that important BUT if SW is involved with some controll systems it will be practical since you can test some of the code. Save for Verilog since you can tune a bit more in the simulation. LTSpice may emulate some of those things with programmable voltage sources .
I need to correct one minor detail. LTSpice is not directly built using the ”original” Spice. It uses the same model language , and of course the same principles. However the internals are different. LTSpice was constructed by Mike Engelhardt as a more numerically stable implementation (faster convergence, among other things). He has now also constructed an improved simulator based on his experience developing LTSpice, the QSpice simulator. This is also available for Free, and even faster and more robust. Unfortunately no longer naitively available for Macs due to the lack of extended floating point registers in the ARM architecture as opposed from the Intel architecture.
Sorry, but I utterly disagree. Nagel and Pederson's introduction of SPICE was a major milestone in EE as recognized by the IEEE organization. The innovation was not " more numerically stable implementation (faster convergence, among other things)" it is the concept, organization, the link between netlist and the solver, components model, subcircuit, types of analysis, dependents sources, and more, and more and more. These were introduced in SPICE and are now implemented in LTspice AND Qspice. I love LTspice and I think the contributions of Mike Engelhardt are immense, as I wrote to thank him several times. But to say that LTspice is not based on the original SPICE is just incorrect, totally wrong, and ungrateful to Nagel and Pederson. See Wikipedia for LTspice: "LTspice is a SPICE-based analog electronic circuit simulator computer software, produced by semiconductor manufacturer Analog Devices (originally by Linear Technology)."
The best LTSpice manual I have ever seen on the internet with the clearlest explanations. Thanks!
Thanks
Really great tutorial, I was looking how to do exactly this and all the methods seemed inefficient. Keep up the great work!
Thanks

Thanks
LTspice explained with examples of actual componens. Thanks Prof Ben Yaakov !

You can change the variable of the X axis. Right click the scale and you will see the window
Works like magIC!

There is no body diode in a SiC MOSFET
Very useful. Thanks again, Professor!1
Thanks
Thank you! What do you think about Qspice compared to LTspice?
I could not see, as yet, any advantage to Qspice

@@Robert88KAL That IS a good feature but for control related simulation I prefer PSIM
thanks professor.

Great! Thats very usefull!
