You can also raise the number under 'MinDeltaGmin' from the default 0.0001 to 0.001, 0.01, or even 0.1. Sometimes it won't work and you can then uncheck 'Skip Gmin Stepping' but that's not advised unless you really need it because it gives non-standard results that won't match reality for the most part. I had to search that one out after getting the error quite a bit. I think you can take the generic xreg and use that but you'll have to define the part with your own spice stuff.Įdit to add that if you get a 'time step too small' error, go to Tools > Control Panel > Spice and choose 'Alternate' under Engine > Solver. If not, grab that library I linked and it should come with it. If it comes with LTSpice, it'll be there. I've had to go and find several other resources to elaborate at times but for the most part, it's all there.Īs far as the 7905 goes, I think that part library has one if it's not in the standard parts that come with LTSpice. It's a good resource for figuring out how the program works. I used the parts from here (self extracting executable that can be opened with 7zip and the like) which I found on the LTWiki. Having said that, I think I'm on the right track for removing the negative supply and having things work. I'm still working on it but I can't get low amperage to behave at shutdown. I'll update when I get it figured out.ģrd edit: I thought I was right but I was wrong on the shutdown stuff. I've tried to pay attention to the limits of the components but may have missed something so if you notice anything odd or off, let me know.Ģnd edit: I found a problem with the bleeder resistor and the base/gate of the transistor/mosfet.

I'm still working on how to get these two consistent but haven't been successful to date. The only issue I've encountered with it in simulation is that when the current is low, the bleed off of the main cap and the other relevant parts of the circuit takes longer than at full current. I've also kept the 12V relay because it helps to shut everything down rather fast.

I've kept the mosfet that was part of the soft start but it's now a transient protection circuit. I've managed to pull out the negative rail completely and I think it might work like this. I've been doing some serious tweaking on this circuit over the last few days and I'd like opinions about anything that won't work or what could be wrong.
