Abstract: In this study, an induction motor is supplied from a SEPIC converter that is extracting a direct current from a photovoltaic solar cell system. The DC output voltage of the SEPIC is converted to a five-level AC output voltage using a cascaded H-bridge inverter. To minimise the harmonic content generated at the induction motor and inverter output, a new topology of "Multi-Carrier PWM techniques" known as the hybrid trapezoidal technique (HTrap) is used to control the switching of the five-level cascaded inverter (MLCI). HTrap technique ensures maximum efficiency of the whole set (PV based SEPIC-inverter-motor) and the lowest total harmonic distortion (THD), harmonic factor (HF), and crest factor (KF). This study also deals with the SEPIC converter performance within the region of discontinuity. Computer simulations using Simplorer 7 or Matlab and Excel have been done to validate the concepts of SEPIC converter and the MLCI with AC motors.
