Abstract
Los sistemas de transmisión de potencia han ganado gran relevancia en el último
tiempo, debido a las ventajas que poseen sobre una conexión cableada convencional,
especialmente en aplicaciones móviles tales como autos elécricos o drones.
Es por esto que resulta interesante diseñar e implementar un convertidor de potencia
sin contactos, para luego caracterizar su funcionamiento y determinar los parámetros que
influyen en su correcto funcionamiento.
Este trabajo consiste en el diseño de un convertidor de potencia que opera hasta
200V/10A para luego conectarlo a un sistema de transmisión basado en dos bobinas planas. A
partir de esta configuración se realizan mediciones con el fin de caracterizar el funcionamiento
del sistema de transmisión.
Por último, mediante la implementación de un circuito tanque resonante conectado a
los bornes del sistema de transmisión, se logra transmitir una potencia de hasta 66,46W a 5cm
de distancia, con una eficiencia total del sistema de 86.3%.
Contactless power transfer systems have gain great relevance in recent times, due to the advantages they have over a conventional wired connection, especially in mobile applications such as electric vehicles or drones. This is the reason why it is interesting to design and implement a power converter without contacts, to then characterize its operation and determine the parameters that influence its correct functioning. This work consists of the design of a power converter that operates up to 200V / 10A and its subsequent connection to a transmission system based on two flat coils. From this configuration, measurements are made in order to characterize the operation of the transmission system. Finally, through the implementation of a resonant tank circuit connected to the transmission systems terminals, it is possible to transmit up to 66.46W at 5cm distance, with a total system efficiency of 86.3%.
