Project Title

DSP based Power Pole Board Design for Power Electronics DC-DC converters

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

DC to DC converters are electronic devices that are used to change the DC voltage from one level to other, analogous to a transformer. A buck converter decreases the level and a boost converter increases the voltage level. Due to the efficiency and voltage regulation benefits in these types of converters, they can be used in commercial and industrial applications. The wide range of DC-DC converter applications are in cell phones, laptops, wind turbines and so on.

These experiments can be done on conventional lab setup like bread board, but other easy and effective option is to design a compact PCB based board known as Power Pole Board. A Power electronic re-configurable board that will enable us to perform several experiments using this power electronics-based board, starting with buck, boost, flyback, forward converters and switching characteristics of Power MOSFET and Diodes and so on. This Power board will help students in analyzing and understanding the concepts of these Converter in an efficient way.

The commercially available traditional power electronics-based lab setup for dc-dc converters are huge and complex, because of having many components so it adds to designing complexity as well. Another thing that it’s cost due to its bulky size and complexity. Also, Efficiency is crucial for a device so interfacing facing FPGA or DSP with power pole board which is highly challenging will also be made simple to improve efficiency considerably. In our locality many Engineering universities and Diploma certifying institutes have laboratory timing for student’s engagement is limited (like 45 min or 1 hour), in such a limited time it becomes difficult for students to learn the concepts. For such cases these concepts of power electronics and studying each of these converters separately is not possible and hence they lose the opportunity to learn.

The solution to all the above problems is a compact Power pole board project, that we are going to develop. It is a re-configurable Power Electronics power pole board that will host many of the experiments. This board will save time of students and is easier way to study concepts of Power electronics DC to DC converters.It can also be interfaced with FPGA board to configure according to the requirement .In this project, we are going to design Power pole board using PCB designing, to make it simple, reliable and cost effective.

Project Objectives

•Designing a Simplified Power pole Board that will host multiple converter experiments.

•PCB designing using eagle software and printing the power pole.

•Interfacing the power pole board-based DC-DC converter to FPGA for its reconfiguration.

•Saving the cost on purchase of converter modules separately using power pole board rather than buying every converter module separately.

Project Implementation Method

•literature review.

• Understanding design requirements of PCB for the board

• Designing PCB for reconfigurable Power pole board in eagle software

•PCB printing of Power Pole Board

• Connection of components in PCB design.

• Testing of Board

• Analyzing results of DC-DC converters.

• Interfacing pole board with FPGA based control board

• Measuring and controlling the output.

Benefits of the Project

1. We don't have any board available in our market and need to order it at cost of 1250 dollars. for that our board has an expected cost of around 10000 to 15000 rupees, which is very cost effective.

2. it has great commercialization potential.

3. It would be more easy to undestand concepts of DC-DC converters on this new board as compare to traditional lab setups.

4. A DSP board or FPGA will be connected to power pole board to improve efficiency.
