Abstract:
The micro-controller that will be designed in this project will allow the user a new level of control over
the way his or her power is to be used. This processor could be used to control all of the households�
power dependent appliances. The program to be written will be completely customizable to the end users needs.
The controller could be used on any type of alternative energy generation that could be applied to a common household.
This design can become very complex while obtaining the appearance of simplicity to the end user.
Project Goals:
This project will be taking the voltage and speed of a synchronous generator as inputs to a microcontroller.
The microcontroller will read these inputs and make a decision. The first set of decisions it will make will
be based on the voltage. For example if the voltage read from the battery is between 11V-14V then all loads
will be turned on. If however the speed of the generator becomes to high, the controller will disconnect the battery
and send the excess power to a dump load while maintaining all other loads. If the battery voltage is between 9V-11V
then the battery will stay connected and all loads but one will be turned on. As the battery voltage decreases the
controller will continue to shed loads based on a preset priority. If the voltage becomes to low all loads will shut off and
wait for the battery to recharge.
