Node 2 is floating - connect a high value resistance between node 2 and ground to overcome this error.
The second problem is with expression used in device Gpm, this is getting evaluated to zero (denominator), you may need to suitably modify it to prevent this.
Gpm plus minus...
Yes. You can easily do that. you need to create a hierarchical block and link you complete schematic to this block. You also need to define interface port on your complete schematic. These port would be considered as pin of top level symbols. refer parts in Data Convertor library...
Export that as csv file. and use configure a file base stimulus in PSpice and configure exported data from MATLAb as input file to stimulus source. You may need to modify the exported data a bit - like adding appropriate header etc to make it valid stimulus
Re: h have a same problam pleas help me whit[ ERROR -- Less than 2 connections at no
Did you get any warning during Netlisting Capture? Also you are running a very old version of PSpice - upgrade to new one or get a free Lite version from PSpice.com
Try reducing RELTOL= 0.005 as against default of 0.001. you can also tweak ABSTOL to 1n instead of 1p. This will loosen the tolerance and thus speed up simulation. however gain in terms of simulation time would be circuit specific. It also seems that your circuit has two very different time...
I suspect the feedback loop may not be working as expected. You may want to try the open loop circuit simulation first, break the loop and run the flyback at fixed duty cycle. This will help get identify the problem if any in power and feedback sense circuit. If this work, you can try closing...
What do you mean by X and Y statement? If you want to define a function and use this for defining some values of components, one can use .FUNC command of SPICE.
If you are looking for Discrete semiconductor like Diode, IGBT, MOSFET BJT etc and some general purpose devices like Opamp, Voltage regulators etc, one can use PSpice Model Editor. In this tool you can directly put value from datasheet to generate Spice model. If you are using 16.6 - with latest...
Yes. This is possible in PSpice. As FvM mentioned you can use G devices to create various types of controlled impedances (inductor/capacitor/resistance). You can refer the following application note for detailed step by step instruction on how to do this...
Yes. This is possible and make sense to look into this. Once simulation is complete, it would be easier for new user to analyze the result and find issues if any.
you can use "PWL Sources" to create a noise source of your choice. Add this in series with your regular voltage source. You can use Place >PSpice Component>Source> PWL Sources to quickly create PWL source mimicking noise.
You can also use alternate way to create this using E devices, - refer...
If you are looking for - How to create a Pulse source in PSpice - Try Place>PSpice Component>Source>Independent Source. This would enable you to quickly define and place source of your choice.
Hope this helps.
Diode model used in circuit seems to be creating trouble, Diode Model DX does not have any resistance (Model Parameter RS) defined, which is equivalent of making it R=0 for this device. Such models are hard to converg. I tweaked this model to have realistic value RS=100U and relaxed couple of...
