Hello Peter
Thank you for pointing out why we need the 15V, I can now see that on the Schematic now. I need to pay more attention, it's always the smaller details that get me.

I have found an adjustable version that could work, I am making sure the ones I have been looking for are around the 3 amps to run everything on the inverter.

I do have some LM2576HV and I have been looking at the datasheet,
lm2576hv.pdf

I am looking to create the circuit on page 22, as I have the LM2576HV- adj, and find R1 and R2 (1k and 12K) that will give a 15V output. Please let me know if I am wasting my time.
Thanks
Andy
