Default Who will model a power supply for me in LT spice for a fixed fee?

Hi folks,

After a lot of faffing, I'm at the end of my patience trying to get a version of LT Spice to work MAC OS.

I am prepared to pay a small fixed fee for someone to model a simple half-wave doubler circuit in LT spice for me, showing voltages and circulating currents. There are around ten components.

I've done the calcs by hand but I think LT spice models the behaviour cycle per cycle and this is what I need... I want to see how close to repetitive stress failure the components will be

Is this ok by the mods or do I need to state the value of the job?

I will exchange emaIls with the person who takes it on, to avoid a lengthy public exchange, and that's how I'll send over a photo of the sketch...

Please reply here and PM me too. Thank you

Send me the circuit, it will be an interesting exercise at least.

Mods, may I add the fee that I'm offering?

£10.

It's not laziness, I just can't get it to work on my Mac and I need to be sure things are within tolerance...

Just bung the circuit up. I don't do LTSpice but I do do Simetrix.

Thank you, Chris. This one’s covered by MM but there will be other circuits needing simulation before long. Can I put you down for the next one?

Always worth asking. If I can find the device models, the rest is easy......

That's great, Chris. It's usually checking stress conditions, transients and peak/surge currents to check within safe operating area.

I'll bear it in mind. Thank you
