Abstract

Eliminating the spurious turn-on in the bridge-leg configuration plays an important role in preventing excessive switching loss, self-oscillation and shoot-through. A passive level-shifter is proposed to superimpose a negative gate voltage to bring down the spurious triggering pulse and thereby avoid the spurious turn-on. The merits of the devised auxiliary circuit lie not only in that it consists only of passive components and can easily be co-packaged into the existing gate driver, but also in that the negative voltage level is tunable and independent of the duty cycle of the converter. The effectiveness of this circuit will be verified by experimental results. © 2014 IEEE.
