Project Summary

To overcome the energy crises in Pakistan, it is the outmost desire to utilize the distributed renewable energy resources. Grid-Tie inverters plays an important rule to utilize the renewable energy resources and generate clean and green electrical energy. The Multi-Level Inverters (MLI) becomes the most popular advancement before few years in the field of power electronics. Due to the utilization of renewable energy resources(PV, fossil, wind etc.) which are the direct source of energy becomes the input of inverter which is DC and several DC sources are connected in cascaded form through semi-conductor switches and produce AC output from it, but it produces some losses and creates THD which decreases the inverters efficiency. This proposed topology of single phase inverter is digitally controlled through FPGA kit which reduces the circuit complexity, number of switches, its loss and THD. As well as it provides noise immunity to the inverter. This novel topology is reliable for medium power applications. The best application of this inverter is that it is tie with a utility grid.

Project Objectives

• The prime objectives of the project is to design efficient, low cost grid tie inverter for Grid –Tie application.
• To design and develop a grid tie asymmetric  multi-level inverter
• The topology must be suitable for medium and high power application.
• The topology will be suitable for distributive energy resources to integrate it with National Grid or micro-grid.
• The topology can also be used to design grid-tie inverter for domestic uses.
• The control of the inverter will be implemented on digital processor like FPGA.

Project Implementation Method

To implement this final year project, it is distributed in the following stages:

• Literature review: In this stage a detail study of existing design  has been conducted
• Design: In this stage a new topology has been proposed and designed.
• Simulation: To check the validity of the design.  The proposed design is simulated using computer simulation tools.
• Hardware implementation: The design has been converted into hardware to further validate the design.
• Testing: After implementation of design on hardware. Different test will be conducted to validate the performance of the proposed design.
• Comparison: The extracted results from hardware prototype will be compared with other existing designs in this stage.
• Documentation: in this stage the whole work done will be documented for submission.
• Submission: In this stage the final deliverable will be submitted.

Benefits of the Project

Benefits of design:

• The design is indigenous and can be easily commercialized.
• Using this design renewable energy resources can be used efficiently to generate electricity.
• The design is efficient and low cast.
• The low rating switches are used as compare to existing inverters.
• The design will inject minimal harmonics into national grid.
• Benefits for community:
• Very helpful to overcome energy crises in Pakistan.
• Energy generated for water pump in agricultural sector can be transfer to grid when there is no need of water for crafts.
• Distributive renewable energy resources can be used to generate clean and green energy.
• A one-time investment.
• Promoting pollution free clean energy.
