    Ground isolation in MULTISIM

    Hello guys, Need the experts help again:) any idea how to isolate grounds in multisim?I have a MOSFET triggered by a pulse voltage..The Source terminal of the MOS is connected to ground. how do i isolate the Pulse voltage's ground and the MOSFET's ground in multisim??any ideas?THank you...

    Current wave in MultiSim Workbench

    Hi Pendragon, THanx for your reply. I managed to get to the device/model parameter option part. Could you please explain again from there?lets say I want to view the current wave near a particular resistor. How do I set it? By the way,u'r second option was wat i actually had in mind, but as u...

    Current wave in MultiSim Workbench

    Hey guys, How do you get the output current wave in MultiSim Workbench? For the voltage wave, I use an oscilloscope,and am able to view a nice wave using the Grapher tool. But how do I view the output current?Is there any tools that i can use?thank you for your time!!!

    Pulse Generator to trigger MOSFET in PSPICE

    spice +pulse generator hello dkace, I did not try the design u gave..it was a bit complicated.But i've sloved the problem..once i increased the trigger voltage for the mosfet..everythign worked perfectly!!:D the trigger voltage was bout 20v..I also rearranged the circuit so it...

    Pulse Generator to trigger MOSFET in PSPICE

    how to trigger mosfet hello dkace, i've uploaded the pspice file.do you mind taking a look at it..i'm kind of a newbie here.. The purpose of a dummy diode is to isolate the trigger circuit and the other circuit rite??how do i place it???thanx for your time.really appreciate this..:D

    Pulse Generator to trigger MOSFET in PSPICE

    pspice vpulse hello there, Thanx for the replyt..actually am creating a multilevel DC Chopper. The problem is,when there's only 1 mosfet in the circuit..the triggering works fine. BUt once i add another layer..the second level that is, the triggering fails..it doesn't provide a...

    Pulse Generator to trigger MOSFET in PSPICE

    pspice pulse generator Hey guys, ANy idea whats the best way to trigger a MOSfet in PSPICE..any in built function generator?i really can't use Vdc(pulse)..anything else i can use in PSPICE?thanx guys..apmreally exhausted fmr trying out with Vpulse,because its not reliable..:cry:

    Power System SImulation SOFTWARE

    Hie, i'm a newbie here. I'm creating a multilevel DC Chopper for my thesis. Problem is, i need to show simulation results for my circuits. I have done the simulation with MATLab but also need to do using another software. PSPICE can't be used, and i'm a student, so cost is a constraint. Am...
