A Modified DC-DC Converter with High Gain Designed for Classical Multilevel Inverter Applications
Main Article Content
Abstract
This paper discusses the operating principle, simulation and hardware execution of a modified non-inverting converter structure with the conventional five level diode clamped multilevel inverter (DCMLI) which is fed by three phase induction motor (IM). The significance of using the conventional multilevel inverter with the proposed converter is to drive the three phase 400V IM from 100V DC source. The proposed converter offers a number of benefits which includes a non-inverting output voltage, large efficiency and voltage gain with low inrush current. The results demonstrated that the suggested approach provides a low inrush current, high gain voltage, reduced voltage THDs and much less flux and torque distortion at lower input voltages. To validate the simulation results of the proposed converter, it is compared with the other presented converters. The hardware prototype of the proposed converter is presented and discussed. The simulation is carried out in MATLAB simulink.
