Carefully read what Eric wrote. There is no measure the temperature.How to measure temperature of a component in LTspice during simulation?
hi,
Press the 'S' key on keyboard.
Enter this line into text box .step temp 0 50 10
This will step temp from 0C thru 50C in 10 C steps
Hmm, I forgot to ask. After I have write the .temp 100 as a SPICE directive, I can just simply use the thermometer cursor to see the watt losses, right?Write .temp 100
I thought that if the component is having a high temperature (100 degree C), then I expected that would lead to higher W losses (heat losses).Why would you expect a large difference?
A resistor will have the same loss.So it really depends on the circuit in question.
Yes, thats is excatly what I want to test. If I force all parts to be 100 C, then I just want to see power dissipation (w losses).We can only force the inside of all parts to be at 25C or 100C or .......
just want to see power dissipation (w losses).
Probably the difference in power loss from 25C to 100C is small.For example mosfets will have higher Rdson, but diodes will have lower forward drop. So it really depends on the circuit in question.
Spice cannot tell you that.If I force all parts to be 100 C, then I just want to see power dissipation (w losses).
I mean the power dissipation/losses.What do you mean (w losses)?
What losses?
Okay, I'm confused about what you are trying to do.I mean the power dissipation/losses.
