Abstract

Parallel-connected inverters are used for high power application. Due to the parallel-connection, there exists a circulating current which does not contribute to the ac side current. The analysis presented in the paper shows that the circulating current is affected by the dead-time. The effect of the dead time on the circulating current for the space vector pulse width modulation (PWM) and a discontinuous PWM is analyzed. The dead-time causes a dc value of the circulating current for the discontinuous PWM. A dead-time compensation technique is used for eliminating the dc component of the circulating current. Experimental results are presented to verify that.
