Current measurement

How to measure current in Pspice?
I need to compare it with an reference current so I can clock some latch.
Thanks
 

Current measurement

Normally divide voltage you measure on resistor and divide with resistance value and you know current passing in that resistor. Even is Spice.

In what situation you want to measure?
 

Current measurement

If I'm mistaken, there are current and voltage probes to measure, isn't it?

Just read your help topics,thats a start. 8)

Use .probe statement:
.probe ID(M1)

I(name): current through a two terminal device
Ix(name): current into a terminal of a three or four terminal device
(x is one of B, D, G, or S)
 

Re: Current measurement

If it is helpfull, you can also add a dummy device to your circuit like a 0V DC source, or negligible resistor.

Some time ago I have worked on PSPICE 9 on defining custoim functions (like the current comparator you mention). I can search on my files (will take some time) If it seems helpful for you.

I need to know inductor current so I can control my actively clamped resonant inverter.

I know what is voltage and current probes and I don't care about current value.
I need to compare it with reference current in order to drive transistors.
 

Re: Current measurement

Pspice can do the jobs you mention, Read the manual you will find out
