Three phase voltage linear induction motors (LIMs) are emerging as a reliable means of providing both fast transport solutions and significant amount of linear thrust. However, conventional Voltage Source Invertor (VSI) and Current Source Invertor (CSI) motor drives applied to LIMs suffer from the generation of harmonic currents from the nonlinear nature of the LIM. This paper presents an improved Quasi-Z-Source Inverter (QZSI) for a linear induction motor (LIM) whose controller has been built, and its simulated results. The proposed QZSI controller herein for a LIM will injects uniformly spaced shoot through states, and promises a high output voltage gain and reduced THD.
