Identification of Dead-Time Influence on The Output Voltage of the Inverter Controlled by Non-Linear Controllers

Abstract

The influence of the dead-time on a inverter VSI output voltage vector controlled by SVM where the switching sequence is defined, is well known. Towards of the inverters used nonlinear controllers, where the sequence of the succeeding voltage vectors maybe of one's choice, the dead-time influence evaluation is different. The method evaluation of dead-time influence on the output voltage of the inverter controlled by nonlinear controllers is presented in the article. The laboratory test results confirm correctness of this analysis and elaborated correction algorithm.
