Abstract:

This paper concentrated on the Z-source inverter applications with reduced inductor current ripples. In order to produce the requirement here in this suggested project implemented an advanced vector control technology for the induction machine applications. The existed PWM converters are designed by the single phase shoot mechanism, in this the time intervals are spitted into six equal parts for the three legs Z-source inverter. The firing pulse generation which is very flexible and simple but in this control algorithm the harmonic content cant minimized. Because the presence of inductor ripple contents increases this causes the necessity of filter. In the filters the utilization of components required more due to this the cost increases. In the proposed model which is operated with the help of vector control method. In this approachment we can control by direct speed control mechanism or the direct torque control mechanism for the production of ripple contents were demagnetized. The simulink models are tested and verified within the MATLAB/SIMULINK models with vector control mechanism with minimized ripple contents.
