Analysis and Performance with Vertical Divided Multilevel Voltage on Phase of Induction Engine

Abstract

In this study, the quality of the transformed energy form is analysed after comparing the single-phase induction motor operated by the SPWM inverter to the 15-level LPWM inverter. Firstly, multilevel inverter and pulse width modulation are designed. The multi-level inverter has sixteen IGBT switches because inverter circuit is constructed with high multilevel inverter topology. Linear pulse width modulation (LPWM) is designed for operation of sixteen switches in the inverter circuit. Secondly, equations of the induction motor are calculated according to d-q axis with creating 15-level alternating voltage. After described equations, 15-level inverter running single phase induction motor is formed at the Matlab Simulink. The obtained results are analyzed according to motor performance and harmonic distortion of the created alternating energy after the proposed model is simulated. Finally, Simulation results of the proposed system are compared with simulation results of SPWM inverter controlling the single-phase induction motor.
