12VDC to 220VAC inverter schematic?

[Faringdon]

Hi,
Does anybody  please have a schem for this inverter (this type of inverter)
Ie, not the type that have a bridge feeding the coil of a 50Hz transformer....want it all high frequency switching type.
..No 50Hz  iron core transformers in there.

There's this but its not too forthcoming...

Page 5 of this seems to be it. Looking for details of the current limiting.

Page 30 of this says the inverter version which uses a Low frequency transformer is more popular....(compared to the high frequency one)...which is very odd?

Is this why we cant find many schems of HF inverters?

The following

..says that LF inverters (with a 50Hz iron transformer) are better for motor type loads, ,where there may be surges.


The issue with high frequency inverters, (ones that dont use the  backward mains transformer)....is that they do not have any transformer, so if a bridge fet fails, then the load will possibly get destroyed...as it will be connected directly to the 350VDC.
