Abstract:
This Seminar report proposes a SVPWM controlled Z-source inverter in its buck
operation state, which is fed to the Induction motor which uses a PID controller for
its speed control. Z-source concept is gaining popularity in modern times as it can
be used in any of the three switching states that is active state, shoot-through state
and zero state unlike the conventional inverters which either buck (VSI) or boost
(CSI). Here ZSI works in its buck region using its zero states properly. Also instead
of using the conventional PI controller, PID controller is used, which has a advantage
of extra derivative part which leads to the anticipation of error in future and helps us
to rectify it before it actually occurs. MATLAB R2010a version7.10.0.499 was used
to simulate.
