Abstract
Hoy en día la electrónica se encuentra en todas partes y es parte del diario vivir. Es por esto que existen diversos tipos de dispositivos electrónicos para una infinidad de aplicaciones, y todos estos tienen algo en común: necesitan energía para funcionar. Una cantidad considerable de ellos requiere llevar la energía consigo para poder operar, por lo que se ha vuelto de suma importancia los dispositivos de almacenamiento de energía. Tanto es así que hoy en día están vigentes varias investigaciones al respecto que buscan encontrar una mejor manera de transportar energía para los dispositivos que lo requieren. Por esta razón es importante considerar todas las alternativas de almacenamiento de energía y sus aplicaciones. Uno de estos dispositivos, el cual se relaciona con este trabajo, es el supercondensador.Este trabajo consiste en diseñar e implementar un convertidor de potencia DC-DC bidireccional que permita controlar la corriente de carga y de descarga de un supercondensador, con la finalidad de tener un dispositivo de almacenamiento de energía funcional, comparable a las baterías convencionales. La primera parte comprende el diseño del convertidor: La elección de la topología y componentes, para luego diseñar el circuito impreso del primer prototipo del convertidor. En esta parte considera simulaciones para verificar el comportamiento del convertidor. A continuación, se comienza con la implementación del circuito en sí, que consiste en soldar las componentes en el circuito impreso. Despúes, se integra un control de corriente que permite controlar la carga y descarga del supercondensador para finalizar con mediciones que corroboren el funcionamiento del circuito.
Nowadays electronics is everywhere and is part of our lives. That is why there are many types of electronic devices for multiple applications and they all have something in common: they need electric energy to work. A considerable number of them require carrying the energy with them to be able to operate and that is why the energy storage devices have become very important. Because of this, several investigations looking to find a better way to transport energy can be found today. Thus, is important to consider all energy storage alternatives and their applications. One of these devices, which this work is about, is the supercapacitor. This work consists in the design and implementation of a bidirectional DC-DC power converter that allows controlling the charging and discharging current of a supercapacitor in order to have a functional energy storage device, comparable to conventional batteries.The first part comprises the design of the converter: the choice of the topology and components. After they’ve been chosen, design the printed circuit of the first power converter prototype. This part also has simulations to verify the behavior of the converter. Afterwards, the implementation of the circuit begins, which consists of soldering the components in the printed circuit. Then, a current control is implemented that allows controlling the charge and discharge of the supercapacitor. Finally, measurements that corroborate the operation of the circuit are taken.
