Project Summary

The project is  summarized as, since the title of the project shows it is about Buck  Power electronic converter and its application as a Power Factor Corrector or abbreviated as PFC. Since PFC’s play a major role in safety of electrical apparatus and also in electrical power distribution and transmission, IEC has standardize what kind of power factor must be sent to the consumer anything not meeting that criteria is not considered and is considered dangerous. As there are multiple topologies proposed for PFC’s but every topology in literature has its pitfalls, in this project we have proposed a new topology of buck converter PFC that works in two modes fly-back and buck mode, in this proposed topology the problem of dead zones in buck converters is eliminated through techniques and the standard power factor is achieved by controlling the On times and Off times of the converter.

Project Objectives

The objectives of this project are as follows

• Study current PFC topologies
• Based on analysis and study of previous topologies propose a new topology
• Simulate and analyze the proposed topology.
• Meet the standard requirements of IEC trough proposed topology.
• Implement the simulated and corrected version of PFC on PCB.
• Analyze the PFC in real world environment.
• Present detailed report and thesis of the fore-mentioned work.

Project Implementation Method

Project implementation started with study of dead zones in buck converters and specifically in buck converter as a PFC, after study and analysis the problem of how to eliminate dead zones of was studied and using power electronic techniques a new strategy was proposed the proposed topology is being analyzed through its mathematical equations and then the proposed topology will be simulated on matlab to check the response and comparison finally the topology will be made into circuit and finally PCB design will be made and presented through EagleSoft software.

Benefits of the Project

The Project is beneficial for safety of human lives and resources the benefits are defined in bullets below

• Project will be beneficial in keeping transmission lines safe
• Project will be beneficial of long term working of apparatus.
• Project will have an impact on growth of society.
• Project will be beneficial in saving resources and health.

Technical Details of Final Deliverable

The final deliverables are mathematical model of a new dead zone eliminated PFC and simulation model of it on MATLAB’s Simulink along with a hardware model on PCB board. The Model will include power circuit of buck converter and L6561 IC as PFC and the deadzone will be eliminated from it the final deliverable will meet the criteria set by IEC FR input PFs.
