LTspice Help (press F1) contains more about the SW model parameters. Assign the MYSW model to the switch symbol S1: right-click “SW” and enter the unique model name, “MYSW”. Control the switch with a voltage source connected to the positive terminal of the switch and ground the neg...

Advanced parametric options for a voltage source.Entering UnitsWhen you enter a parametric value in option field, LTspice follows standard...
第一, 首先再重复下仿真的意义:仿真,一个古老的话题,我之前说过仿真是YY, 不如实战, 但有些时候,...
To build his model, he’s using LTSpice, a free circuit simulation program. Using voltage to model temperature and current to model heat flow, he’s set up a model for his home to compare the behavior of a heat pump and a propane furnace. A switch model already in LTSpice with built...
Thank you.It works.But I still want to see the current of magnetizing inductance.If i need to use Pspice to simulate L3 model?Actually Its not my first time to have the error with L3 model.Are there any tips for adjusting parameters of .options syntax?I'm not sure I understand your ...
In order to switch ON the MOSFET (to make MOSFET operates in saturation mode), the pulse amplitude must be greater than threshold gate-to-source voltage (VGS(th)). According to datasheet of the MOSFET model IRFP054V [5], VGS(th) for the MOSFET is between 2 V to 4V. Therefore, ...
Failing to find a model for a momentary-contact pushbutton switch, I tried to see if I could use LTspice's voltage-controlled switch. (See attached .asc file.) I failed. Problems: 1. The VCS seems to be undefined when plopped down in my circuit. When I try to run the simulation LT...
> Would modifying those parameters throw up functional simulations but that show 'false' results? Does your simulation duration give U3 enough time to start up? > Does U3 datasheet give you any clues as to why there is 'trouble with U3'? 40u/5n is 8,000 points - does LTSpice like ...
If you don’t have the time to dedicate to studying, the second approach is to go directly to a component’s datasheets. Be sure to look at Vishay’s document “PTC Explanation of Terms” [2], which describes the numerous PTC parameters, fromTsto the voltage-dependent resistance (VDR) ef...
