I re-did the frequency test but with AC output voltage = 200 V RMS (instead of the above test using 230 V RMS) No ugly things at 40Hz! Of course, it was saturation. Now ugly things happen at 34 Hz @ 200 V AC RMS It's strange though, I see beginning signs of saturation when running this toroid at 50 Hz and 230 V RMS. Not a lot but it clearly reduces as I increase frequency to 55 Hz. It seems there is a little room for further optimisation of the inverters. wronger than a phone book full of wrong phone numbers
