In Ttype converters， to avoid the power switches of the same leg to conduct simultaneously during altering the power switches， the deadtime has to be inserted into the switching sequence． However， the inserted deadtime increases the current THD and reduces the output voltage and current． In this paper，an approach which integrates deadtime elimination and compensation is proposed to remove the adverse effect of deadtime based on the function of the deadtime． When the phase current is much larger than the phase current ripple，the deadtime elimination is applied to avoid short circuit without dead time． When the phase current is near zero-crossing point， the deadtime elimination is inapplicable because of the disturbance of current ripples，and the deadtime must be used to improve the stability of inverter． Therefore， the deadtime compensation is used to remove the adverse effect of deadtime． At last， the experimental results demonstrate that the proposed approach is an effective solution to the problems caused by deadtime
