MULTILEVEL CONTROL STRATEGY FOR INDUCTION MOTOR USING PV-BATTERY STANDALONE SYSTEM

The paper presents a scheme that is used to enhance the capacity of the PV cell along with standalone battery used to feed the induction motor drive. The power capacity is increased by using 9-level inverter and its is almost equal for the cases of Neutral Point Clamped Multi level inverter and Cascade –H –Bridge inverter. Since the power level remains same for the above mentioned topologies, here main focus is on the THD content for the different topologies.
