- LT Spice error - Electronics Forum (Circuits, Projects and . . .
Simulate -> Control Panel -> SPICE tab then change the Solver [*] engine from Normal to Alternate This flushes out most 'time step too small' errors This is all assuming you dont have, say, a floating node, a short circuit that is demanding infinite current (or infinite rise time), or something is generating an infinite voltage somewhere
- Building a circuit that involves solid state ralays and 555 timer.
Hello guys! I am trying to build a circuit and had been thinking about it for a few days but came out with no solutions I am trying to build a circuit of which when a button is pushed, the 555 timer which is to be configured as a one shot multivibrator will send out an output for 3 seconds
- Totem pole PFC using GaN on LTspice
Hi I am trying to simulate a Totem pole Boost PFC circuit using GaN switches on LTspice I am unable to achieve the DC output and the circuit is also not boosting up the input voltage Any suggestions to make my circuit work will be a great help I have attached my circuit here Thanks in
- OrCAD simulation help | Electronics Forum (Circuits, Projects and . . .
Could someone give a detailed guidance on how to simulate the following project in OrCAD Capture CIS Lite step by step? Draw a schematics for static analysis of a diode Simulate the circuit such that static characteristics of forward biased 1N4002 diode for three temperatures (75 , 25 and 125
- Simple crystal oscillator simulation in LTspice
I'm attaching an LTspice file that simulates a crystal oscillator with resonant frequency 1MHz, and it works fine But if I change L1 from 2 5 H to 9 8 mH to simulate a crystal oscillator with resonant frequency 16MHz, it flat-lines (no oscillations) If I replace the CMOS inverter with a custom
- Light Controlled Resistor Simulation | Electronics Forum (Circuits . . .
I'm using SPICE to simulate a circuit with a fair amount of complexity The actual circuit has a light controlled resistor in it which is crucial for correct operation The light that controls the LCR is not simply on or off The voltage drop will change dynamically and thus vary the
- 4046 simulation, 74HC4046 simulation - Electronics Forum (Circuits . . .
Look this model not work properly I simulate days and days, and results are what they are Then I think simulate it step by step, first "how VCO work" Using days google I found it secret formula: fmin = 2 (C1R2) fmax=2 (C1* (R1IIR2)) Eg this 82 kHz I can try eg fmin 60 kHz, fmax 120 kHz With this frequences 470 pF looks good Using formulas I found R1 = 35k and R2 = 71k Formula
- Motorcycle CDI Pulse output | Electronics Forum (Circuits, Projects and . . .
I am building a project where I need to simulate a single Charge Trigger coil of an AC CDI My thinking is to convert a Hall sensor output to obtain pulses, both positive and negative, equal in size of around 400 volts, which will feed the original CDI The signal would originate from a Hall
