  • How to simulate 3 phase (symmetrical ) circuits on LTspice?
    In class, these values are in degrees and not seconds so I'm confused If I'm using the correct value in LTspice The simulation does not seem to work Ic should be furthermore delayed than Ib and not be on top of each other What am I doing wrong, and what is the proper way to simulate 3 phase systems in LTSpice? Thank you!

  • Microcontroller simulation in ltspice | All About Circuits
    LTSpice is not really intended for doing digital simulation and, AFAIK, only has a pretty rudimentary ability to do digital behavioral modeling Trying to simulate all but very small digital circuits with an analog simulator will quickly bring them to their knees because of the sheer number of transistors involved

  • Good tutorial how to create new model in ltspice
    There a several good books on device modeling for SPICE Depending on the version of Spice (LTspice TI spice NI spice etc ) your models will have various caveats However to answer you question about good books, here you go: 1 Giuseppe Masspbrio and Paolo Antognetti, "Semiconductor Device Modeling with SPICE", 2nd ed , ISBN 0-07-002469-3 2 J
  • LTspice modified relay models - All About Circuits
    I modified the LTspice models I have for SPDT and DPDT relays to make their coil operation non-polarized (typical of most standard mechanical relays), and added hysteresis to their energized coil voltage (≈74% of rated voltage), and de-energized coil voltage (≈25% of rated voltage) As before

    Old troglodyte that I am, I'm still using LTspice IV since I prefer it's interface and I know it's hot key designations And one big annoyance to me is that 24 doesn't remember my settings when I switch between AC analysis and Transient analysis, whereas IV does
  • Crystal controlled oscillator modelling in LTSpice
    The bypass is available in Qspice and LTspice It's just different In Qspice the inductance is shunted more strongly That's why I made Rpar=0 Pay closer attention to the difference of amplitudes! In LTspice the amplitudes are smaller! This is because of the shunt mentioned above Make Rpar=0 in LTspice and you will get the same result as in

  • LTspice - Closed control loop for LLC converter - All About Circuits
    Unfortunately I don't know how to it in LTspice I looked up on the web as much as I could and came up with few ideas: - using LTC 6992 that has ability to change frequency based on resistor aplied to Rset pin, - using "modulate" block from LTspice library (but as far as I know it has sine wave as an output),
