Abstract :
Inverter flux control methods directly control the integral of the inverter output voltage vector, by means of the inverter switching. These methods have found applications in low- and medium-voltage industrial drives, and in inverters with outputs connected to the utility mains. This paper describes a new method for the direct control of the inverter flux vector, with the viewpoint of using this vector as the main forcing quantity in a closed-loop control system. It illustrates the use of the inverter flux in the control of a utility-connected inverter
