I have found that for motors and transformers these seem to work fine with the transformer/motor not overheating due to the imperfect sinusoidal waveform (modified square wave). I have adjusted the frequency of the inverter that I picked up from Canadian Tire (Large chain auto supply example) as it used a pretty basic IC oscillator circuit and after downloading the schematic and suggested uses found the resistor that I could adjust frequency. I see no reason this would not work for larger inverters (500 Watt). Or buy a North American inverter (115V 60Hz) that is the correct wattage... Then all you need is a hefty 12VDC supply and I used a computer switching supply - they pump out lots of amps on the 12V line these days. We installed a couple of these in jukeboxes going to the orient and they provided all the power for the machine - set the computer supply to 220 and they are still going strong...
