Progress Presentation

Today, we presented to our lecturers all our work to date. The reasoning behind our presentation is to help keep us on target. It was a wake up call as it was my worst presentation that I have ever participated in. Not only was I late, I was also ill prepared. I felt like a robot without a brain and when it came time for the lecturers to provide their feedback, lets just say we had a lot of constructive criticism. 


If we are to move on from today, we need to pick up the pace, put our heads together and get the work done. I hope to meet with Azizi in the holidays to complete the majority of the practical work done so that we may begin with our written report.

Circuit Operation

During normal vehicle operation, the suspension oscillations will cause the generator to jounce up and down in a vertical motion with the vehicles unsprung mass due to the generator being fixed to the vehicles chassis. This causes the rotor to simultaneously pulsate in and out of the coil windings, thus cutting through the lines of magnetic flux and inducing a current and AC voltage in the copper wire (stator). 


From the stator, current conventionally flows to the bridge rectifier, where the AC voltage is converted to workable DC voltage. The output voltage then flows to the capacitor and begins to charge it. Once the peak charge threshold is met then the current is redirected to charge the battery.
