i've a reverse polarity protection , i want to check inrush current simulation , but i don't know how .

i read this , but i tried but doesnt work

How to plot voltage vs current graph on Proteus Software?


update :

i have removed resistor caps , put resistor load , and that what i got for simulation :

enter image description here


update 2 :

i have made sweep analysis : increase battery voltage from 0 to 48 , and monitor it with monitoring resistor voltage

enter image description here

is that simulation right ?


update 3 enter image description here

  • \$\begingroup\$ You need to get ride of C4 and C3 and make C1 and C2 the same value but, a 1 farad value is likely to be too high. If you can plot output voltage across the load resistor, that tells you what the inrush current profile is. \$\endgroup\$ – Andy aka Feb 16 '20 at 10:03
  • \$\begingroup\$ so its wrong to model load circuit with current source ? or it should be resistor across current source , or only resistor ? \$\endgroup\$ – Ahmed elmenshawie Feb 16 '20 at 10:08
  • \$\begingroup\$ You should model your load to how it really is but, to measure inrush currents you can model as a resistor. Let’s keep comments away from the previous question for my sanity on my small tablet because it’s hard to track where I am on the small screen. \$\endgroup\$ – Andy aka Feb 16 '20 at 10:12
  • \$\begingroup\$ yes sure for comments on this question , i have updated my question, can u please check it \$\endgroup\$ – Ahmed elmenshawie Feb 16 '20 at 10:17
  • \$\begingroup\$ Ok, here’s where I can’t help Much. I don’t use proteus but, if it’s anything like micro cap, when you do a time or transient analysis, it might default to showing you a graph of the output voltage after it has settled down. In micro cap this is disabled by a radio button such as “start analysis from true zero” or words to that effect. \$\endgroup\$ – Andy aka Feb 16 '20 at 10:22
