Performance analysis of SVM control of cascaded seven level multi string inverters for industrial drives

Abstract

This paper presents the performance analysis of space vector modulation control in seven level multi-string inverter. The seven level multi-string inverter is also used in industrial drives at various load condition. The output voltage and THD value of the various load condition is studied and it is tabulated below. The performance of five level and seven level multi-string inverter are compared and its output and THD values are tabulated below. To study the importance and advantage of space vector modulation control technique, the seven level multi-string inverter is implemented other PWM technique and its THD and output results are compared and tabulated below.
