Abstract

The proposed research involves the design and implementation of a novel hybrid topology for power quality improvement using multilevel inverter fed induction motor by reducing vibration for Textile applications. Various modern applications have started to require higher power gadgets as of late. Staggered inverter is equipped for giving wanted substituting voltage level at output utilizing different low-level DC voltage as an input. In H-connect staggered inverter, the quantity of output level is characterized by the quantity of exchanged capacitor cells. A small amount of voltage can be utilized to produce a supported output voltage by exchanging the capacitor in parallel and in series. Staggered inverter produces less Total Harmonic Distortion (THD), less electromagnetic interference and less voltage inrush on switches. The proposed topology delivers a staircase waveform with higher number of output level utilizing less segments contrasted with a few existing exchanged capacitor multilevel inverter. The task manages cascaded H-connect staggered inverter that can be utilized for both single and three stage change. The structure is created with H-bridge inverter including DC-DC converter. A sine pulse width twist is decided on PWM pulses. The inverter essentially takes care of the issue of capacitor voltage adjusting as every capacitor is charged to the esteem equivalent to one of the information voltages at each cycle. Recreation is finished with the assistance of MATLAB Simulink programming and the exploratory outcomes for current and voltage at various THD esteems are appeared and the equivalent is done for equipment. The prototype structure is conceded and analysed for various parameters of proposed method, which results in reduced switches and proves more efficient than other conventional methods and in addition it is more proficient for pumping process in textile industry for wastewater treatment.
