【Abstract】 The paper discusses in particular and analyses quantitaively the effect ofvarious loss of the sinewave inverter operating on different conditions of theload.It is pointed out that major factors effecting efficiency of the inverterare the loss of the transformer and the power switch transistors.Theimportant reason of effecting efficiency of the inverter operating on lowload is the power loss of the driving circuit and the controlling circuit.更多还原
