Operational analysis, performance evaluation and simulation of solar cell powered embedded EZ-source inverter fed induction motor

Abstract

This paper presents the operational analysis and performance evaluation of solar cell powered embedded EZ-source inverter fed induction motor. Embedded EZ-source inverter (EZSI) produces the same voltage gain as Z-source inverter (ZSI) but due to the DC sources embedded within the X-shaped impedance network it has the added advantage of inherent source filtering capability and also reduced capacitor sizing. This is attained without any extra passive filters. These advantages are significant for applications like photo electric and wind electric system. The operational analysis and simulation results exemplify that an EZSI is the most promising technique for renewable energy applications in order to reduce the overall system complexity and thereby improving the inverter efficiency. © 2013 Springer Science+Business Media New York.
