Project Summary

Conventional rectification by using bridge circuit and a low pass filter can affect the quality of power on AC side by injecting significant harmonics in line current. Currently large number of devices require AC to DC conversion, which results in significant effects on power factor, line losses, RMS line current and its shape.

Rectification done through conventional method produces spikes in line current, which loads the source and in fact have worse effect on power converting machinery and its performance.

The aim of this project is to design an efficient AC-DC Converter that will minimize the effects of conversion on power quality. The solution will be based on power processing consisting of power controllable switches. The system model is shown in figure. Prototype of the proposed system will be built to verify the design.

Project Objectives

The objective of this project is to design a power factor correction (PFC) Converter based on a power processing technique. The design objectives are power quality improvement by achieving a power factor of 0.9 or above.

The main objectives of this project include the designing of a system which can effectively use the renewable energy resources based on induction generation or AC sources to feed the DC microgrid and minimize the energy conversion losses to deliver quality power. It also includes to deliver such a system which will help to cater the increasing demand of electronic equipment and a maintenance-free system which can be left unattended.

Project Implementation Method

We will follow the general technique to solve a certain problem in which we will start with the identification of problem. Then we moved to the literature review phase in which we studied and analyzed the work of others. Like how they implemented and how much efficiency they achieved and which technique they employed. In the next phase we formulated the solution on the base of literature review. In this phase we also derived the equation for implementation and done mathematical calculations. The next phase is simulation in which we checked the working of our proposed solution by the help of computer simulation techniques. After the successful simulation we will verify the results. Next phase is hardware implementation which is based on simulation and calculations. We are in this phase and have implemented some parts of the project and work is still in progress on final hardware and controller. In this ongoing phase we will check the working of hardware and rectify the problems which will arise, tuning of controller will also be done for desired result. After all the successful hardware implementation the final task is to assemble the hardware in the presentable module and complete its documentation for Final presentation.

Benefits of the Project

Although AC-DC conversion is required in many applications like mobile phone charging, led lights, laptops, Inverter AC and several other applications.

One bigger application requiring large amount of power to be converted from AC-DC will be electric vehicle charging (around 6.2KWh, fast charging mode). If it is done by using conventional techniques it will result in severe degradation in power quality. The proposed solution is also desirable for upcoming microgrids based on renewable sources.

In a bigger picture AC-DC conversion is required in almost every device or machinery and has vast applications. So, the combine effect of all the rectifying devices on source will be very adverse. That is why our main objective is to improve our converter system for high efficiency so that we can implement on smaller scale to larger scale for the better and quality energy conversion and compete with the increasing need of energy.
