    I need to simulate a power electronic circuit of a battery charger for my project. what will be the most suitable software for this? will a free student version sufficient for the task? (circuit contains LM350 and LM741)

    LTspice lacks any models for switches ... very odd.


    TINA-TI has switches and the LM741, but I'm not seeing the LM350.

    It seems like there's always some problem with free tools. Though not enough problems for me to want to pony up some cash for a professional tool. ;)

    LTspice does have a voltage controlled switch (SW).

    I do not use LTspice myself. But does not LTspice allow the use of external/imported spice models? You can not expect a simulator to have every component in the library. So the skill to import other spice models are important

    Shane7. Give us your circuit and we can try to see
    what can be found.
    I have used Paul Falstad "circuit"
    to simulate a 240Vac to 12V dc regulated.
    To what level are you working?:D
    LTSpice is pretty good, for free.
    I use Tinycad for my schematics, also free.

    Take care.

    My proteus simulator dont have LM350 (3A) but it has LM317K and LM317T which I think is similar to LM350 except the current is only 1.5A. Would that be OK with you?

    You can get the demo version of proteus from Labcenter UK here
