| Summary: | This thesis is about a research project entitled An Investigation On-Board Recharging System for Portable Battery Operated Vehicle. The importance of this research is to prove that the life of the battery can be expanded during the operation by reducing the frequency of recharging time. This can save the electrical energy which then saves the cost. In this research, a dynamo was used as a significant charging device from which it can provide a small voltage output. In this research two methods were used to rotate the dynamo. Method one or Experiment 1 used wheel of portable vehicle while Experiment 2 used bicycle's perwel and bicycle's gear. The output voltage from the dynamo was connected to the rectification circuit to convert an AC voltage into DC voltage. The DC output voltage was rectified and increased by using boost converter, which aimed to step up small value of voltage to higher voltage. Within this circuit, there was a JFET driver which was used to provide clock cycle for switching. From these two experiments, the first experiment gave better results where it produced higher voltage and current output as compared to the second experiment. The results from both Experiments 1 and 2 were compared with theoretical assumption using Orcad PSpice simulation. The research gave the researcher the idea on how to improve the life ofthe battery. |
