audioguru Posted March 30, 2007 Report Share Posted March 30, 2007 150W output plus 38W of heat in the inverter circuit = 188W total.188W/12V= 15.7A from the 12V battery, into the low voltage winding of the transformer and is the average current in the Mosfets.15.7A is the average continuous current, the peak momentary current is higher.If you overload the transformer or the Mosfets then they will overheat and fail.
