Current direction

Hello,

I am new to PSpice.

I like to see the direction of currents. In the web there are picures showing this (minus or nothing befor value), but I couldn't find any option to get this done ?!

Help :-)

Hi,

It appears per default. You visualize the DC current clicking PSpice --> Bias Point --> Enable Bias Current Display or in the probe window with a current marker (PSpice --> Markers --> Currento into pin). take into account that current is measured from pin1 to pin 2.

Hope it helps.

Hi,

Thanks for the insights, but i was modelling gate driver which has high and low side FET which i am modelling it as switch and VPWL device to obtain I/v curves in 1st and 3rd quadrants i am confused with current direction which Pspice is taking (Current entering and current leaving)

1)Switch S3 + pin is as current entering a pin when i probe current it gives positive current direction ((V6 =1)

2)Switch S4 - pin is indicated as positive so when i probe this pin it shows positive current direction (V6 =0) 

I am DC sweeping V7 from 0 to 8V

Can anyone please give some sense of direction in terms of measuring current and its direction in Pspice

Hi Adithya,

When you see two different signs of current, it basically means that the actual current is flowing in the opposite direction (PSpice basically compares it with its assumed current direction). If its in opposite direction, it gives it a negative sign.
