A 54 pulse AC DC converter fed 7 level inverter based vector controlled induction motor drive
A 54 pulse AC DC converter fed 7 level new cascaded voltage source inverter (VSI) based vector controlled induction motor drive (VCIMD) is presented in this work. An extended delta and delta polygon configured transformer based 54 pulse AC DC converter is used at the supply end to reduce total harmonic distortion (THD) of the utility current within limit as specified in an IEEE 519 standard. The steady state, dynamic and power quality performances of an induction motor are improved by a 7 level new cascaded inverter. Two separate and dependent algorithms are used to control an induction motor and a 7 level cascaded inverter. A delta polygon based 54 pulse AC DC converter fed 7 level inverter based VCIMD is modelled and its performance is simulated in Simulink/MATLAB environment to demonstrate its effectiveness.
