Abstract(s)
O facto de a energia elétrica ser um tópico de discussão global, faz com que a transmissão
de energia sem fios torne-se cada vez mais relevante devido às vantagens que esta
apresenta nas suas aplicações. Nesta dissertação é estudado e implementado um modelo
de um circuito de transferência de energia sem fios através de uma simulação
computacional e um protótipo preparado para fazer a transmissão de energia sem fios por
acoplamento indutivo ressonante. A parte fundamental do sistema proposto integra dois
pares ressonantes de condensadores e bobinas. O circuito de potência utilizado baseia-se
numa ponte H utilizada normalmente para motores de corrente contínua. Para o controlo
aplicado à ponte H é utilizada uma função oscilante presente no Arduíno cuja frequência
de oscilação pode ser regulada de acordo com a frequência de ressonância do circuito.
Foram feitas as aquisições de resultados em contexto experimental, os quais são
comparados com a simulação realizada no programa MATLAB, respeitando as condições
da topologia inicialmente escolhida.
The fact that electrical energy is a topic of global discussion, makes wireless energy transmission increasingly relevant due to the advantages it presents in its applications. In this thesis, a model of a wireless energy transfer circuit is studied and implemented through a computer simulation and a prototype prepared for wireless energy transmission by inductive resonant coupling. The fundamental part of the proposed system integrates two resonant LC circuit. The power circuit used is based on an H-bridge normally used for direct current motors. For the control applied to bridge H, an oscillating function present in the Arduino is used, whose oscillation frequency can be regulated according to the resonant frequency of the circuit. The acquisitions of results were made in an experimental context and compared with the study carried out in the MATLAB program, respecting the conditions of the initially chosen topology.
