Electrical/Electronic Engineering

Project Summary

In this project we will design and implement pure sine wave invertor by achieving five levels. This invertor will run AC appliances at a low cost with high efficiency, the invertor will comprised of four power MOSFET in a single H-bridge configuration and pulse width modulation technique will be used to derive the MOSFET, at the end a low pass filter will be used to filter out the high frequencies and thus in isolate the harmonics so a 50HZ fundamental frequency can be retained.

Project Objectives

  Main objectives/goals of the suggested research are listed below.

• To investigate different techniques for Multilevel inverter
• To generate a 5 level multilevel inverter  output with low distortion through SIMULINK/MATLAB
• Hardware implantation of 5- level multilevel inverter  using microcontroller
• Harmonic content in the sinusoidal output is low compared to conventional invertors
• Minimize switching losses
•  

Project Implementation Method

A small number of voltage levels of a multi-level inverter using series inverters with independent separate DC power supplies is five. In order to achieve a five-level output waveform, a full-bridge electrical inverter is used. The circuit is consist of typically four main switches which is MOSFET and four resisters act like freewheeling diodes which is also known as H-bridge inverter By turn ON and OFF the appropriate switches, each H-bridge inverter should produce three different voltages which is +Vdc, 0 and –Vdc. So When the switches S1 and S4 are OFF, then the output voltage is +Vdc. When the switches S2 and S3 are OFF, then the output voltage is –Vdc and when either the switches S1 and S2 or the switches S3 and S4 are OFF, then the output voltage is 0.

Benefits of the Project

• By increasing level  harmonics will reduce from sinusoids and will get pure sinusoids.
• Reduces audible and electrical noise in fans, fluorescent lights, audio amplifiers, TV, fax and answering machines.
• Inductive loads like microwaves and motors run faster, quieter and cooler.
• Prevents crashes in computers, weird print outs and glitches in monitors.

Technical Details of Final Deliverable

The appropriate method to minimize the number of switches with least amount of supply a higher number of active switches to perform power conversion in small voltage steps so the smaller steps tend to lead the production of higher power quality waveform and also reduced (dv/dt) on the load and electromagnetic compatibility, for this purpose the topology of utilizing low switching frequency high power applications. We are going to generate 5-level multilevel inverter there topology has modification with which we reduced output voltage distortion.  The harmonic distortion decreases as the number of levels increased in Inverter. Pulse width modulation (PWM) techniques increase the control complexity and the switching frequency to achieve pure sine waveform.

Pure sine wave inverters are capable of producing cleaner, smoother, quieter, and more reliable electricity to operate appliances and electronics without interference.
