I suspect I may have had a 'senior moment' when calculating the transformer turns ratio . The calculated flux density is 0.96 Tesla. Can somebody please confirm these measurements are correct for a 48V inverter: Powering the output winding with 235V AC I measure 26V AC at the input winding. Everything else was disconnected from the transformer for this test. The magnetising current was 136mA, this is about right for this 6KW toroidal core when compared to my other 6KW inverter.
