simulation

Hi, I am only on my 5th week trying out TinkerCAD for our Logic Circuits course. We are tasked to create a 7-Segment Display Using Logic Gates only. I did all the boolean expressions needed for each segment using K-MAP, and identified the boolean expression needed to create my circuit. I am...

I am trying to simulate a Phase shifted full bridge converter in LTspice. I had already simulated it in matlab simulink and obtained the desired results, but I am redoing it in LTspice to include the effects of non-ideal components. In order to avoid the pulse generation, I imported the...

I have obtained a LTspice file from the net, its a .asc file but its in the form of the following text. I cannot for the life of me figure out if there's a way to convert this to schematic and run it as a simulation file. Please help. Version 4 SHEET 1 1180 680 WIRE -352 -288 -416 -288 WIRE...

Hi its a boost converter circuit. its mean it make increase applying voltage on the output . I am applying 201.6 volt and I should see approximately 650 volt on the output. But I have a problem about capacitor. When I use basic capacitor, I realised that my capacitor is not working well...

Hi I am studying a dc dc converter model. My friend drew this circuit and got this graphic. I added his circuit and graph . But I draw same model , same numbers for resistors capacitors v pulse source ,inductor, diode but my graph is very different. Actually my V pulse source looks like doesn't...

How does LTspice search for symbols and subcircuits? Is it different for automatically generated symbols and Out of the box symbols? I ask because I ran into an error message that states "Could not open library file "C:\users\*****\Documents\***etc". This was when I tried to run a new project...

Hello, I have tried to add the schottky diode(spice model from onsem) as you can see on the schematics on LTspice but I keep getting the same errors and I have watched the intro from this link : Adding Third-Party Models to LTspice IV but I still get this error I have saved the same schematics...

My simulation with a dc forward converter has a problem when I add any parallel capacitance to the inductor L3 even when I add a real diode after the L3, the problem with the parallel capacitance is that surge an extremely high peak current in the MOSFET, I don't think that's suppose to happen...

Hello, I want to design a battery simulator circuit to test my board. My board connects to a single cell li-on battery, 3.8V 2400mAH and it has a wireless charger circuit with up to 400mAH charge. The battery simulator needs to provide up to 1A to the board and to be "charged" at 400mA. I've...

Hello everyone, I'm new here. So I've got this assignment that asks me to use JK flip-flops in order to create a circuit that obeys the following truth-table: The thing is, I have no idea on how to get these results at all. From what I understand, first two lines imply that PRE and CLR are both...

Hi, My project diagram is similar to this idea, Lets say input is 3p 380VAC, 60Hz, Main Transformer MTR runs at 20kHz, DC output should be 50-147 v, charging current 100A. Should have CC and CV mode of operation. I need to implement FW with following facilities, 1. Shunt/ Temperature...

Hi I am trying to make a dimmer circuit with proteus. But it is not working according to our calculations. I am very new both in proteus and also learning about OP-AMPs. So I am not understanding what's wrong with the schematics. Both the current and voltage is showing zero. Here is the...

Dear all, I am trying to simulate my synchronous buck converter and I managed to implement complementary signals to driver two different transistor. The issue is as follows: 1- I inserted dead-time (green circle) but the problem is that at the start of the period two signals overlap...

What I'm trying to do? I'm making a constant-current source based off an existing design. The specs of the existing design are: Existing Design The design is of a constant current source capable of outputting 4-20mA output current from an input voltage of 0-2V. The Problem The problem is...

libvmcu - Virtual MCU Library libvmcu is a library for static and dynamic analysis of AVR binaries. It can be used to create regression tests for embedded systems or to analyze AVR programs on assembly level. You can build your own tools too. There is also a Java binding, that supports...

1. So Vim has vimscript, Emacs uses Lisp - what is LTSpice doing? 2. You can use .step to update a {R} for .meas and calculate MAX/MIN etc - how is the data being passed and how do the various directives influence each other? Note in the schematic, he uses {R} and 'r' and R1 and they are all...

Hello. Thank you for clicking on my article. I'm from Korea and a college student. I'd like to find a solution. My circuit simulation speed is too slow. So I want to speed up. I saw what other people did at Google and made it. I want to speed up the simulation. I'd appreciate your help.

So I have this simple resistor divider circuit in PSpice/from a book/NGSpice - how do I load it in LTSpice/Linux/Wine? (I'm reading from SPICE A Guide to Circuit Simulation but I am also reading from Passive Circuit Analysis with LTSpice. The former has the example) I tried manual loading in...

Hello all, I don't know if i am supposed to ask this kinda questions in this thread but i am going to anyway! Tried importing a spice model for BAV70 (Dual-diode SOT23 package) after seeing some tutorials, all of them use a a generic component that represents the symbol of the SPICE model...

Hello. I am working on extracting strain gauge values mounted on my ATV (front suspension) with the help of a 20 bit ADC of PSoC. Before that I would like to simulate it. So could you please suggest how can I do this in proteus(or any other SW if not possible). Please help. Thank you for your time.
