PM starts presentation. Everyone speaks. You decide who goes when.

2. Project Overview
We were tasked with building the power integration system to be implemented in a solar car.
This system consists of
A solar controller to control when to charge the batteries and when to not
A motor controller that will control the output of the motor based upon a throttle position sensor
Give a brief overview of your project, like a very concise executive summary.

3. Project Motivation The problem:
We want Texas State to compete in the ASC!
Need to go green!
Brings in interest from prospective donors and students!

6. Results
The Results:
Motor Controller easily controlled motor with 144 V battery pack attached
Able to have motor run at ~5000 RPM
PWM controlled and completely isolated!
Solar Controller able to switch on and off at 137.9V
Reducing the power initially needed from 200W to ~160 mW
Completely isolated!
BRIEFLY summarize the results of your work – and what your design will do. USE GRAPHICS and PICTURES! Be visual!! Add slides if need be!!

12. Future Work
A DC to DC Converter is needed to step down high voltage, 138V, to usable voltage, 13.8V, for instrumentation.
There will be other senior design projects to build the solar car.
The power integration system is just the first step in building this solar car.
Our project will be handed off to future senior groups to be implemented with their projects.
BRIEFLY give 2-4 bullets of future work. BRIEF
