Sistema de controle de energia para veículos de recreação

Abstract

This project presents the development of an electronic circuit for power control used in recreational vehicles (motorhomes), which is an electronic device able to automatically control the output of auto-transformers used in these vehicles. It was developed a system using thyristors to control the batteries charge. After this phase, a system for voltage adjustment was implemented using contactors in the input adjustment gates of the auto-transformer. To identify the voltage supplied to the system by outside sources, a voltage switching electronic circuit using a PIC microcontroller was developed. For controlling the system, a software was developed using C language for the microcontroller, which automatically manages all the others peripherals systems. In the final phase, all the processes and systems mentioned above were integrated, resulting in the complete hardware. This device was developed in order to provide satisfaction for the users of recreational vehicles, ensuring efficient control of power supply and thus maximizing the lifetime of components used in these vehicles.
