Este artigo apresenta um método de projeto de um sistema de transferência de energia sem fio (WPT) de dois saltos para instalação em um braço de robô. O inversor classe E e o retificador classe D são utilizados nos lados de transmissão e recepção, respectivamente, no sistema WPT proposto. As equações analíticas para o sistema WPT proposto são derivadas em função dos parâmetros geométricos e físicos das bobinas, como o diâmetro externo e a altura das bobinas, o diâmetro do fio do enrolamento e o número de voltas. Usando as equações analíticas, podemos otimizar o sistema WPT para obter os valores de projeto com a eficiência de fornecimento de energia teoricamente mais alta sob a limitação de tamanho do braço do robô. Os experimentos de circuito estão em concordância quantitativa com as previsões teóricas obtidas na análise, indicando a validade do método de análise e projeto. O protótipo experimental alcançou 83.6% de eficiência de fornecimento de energia na frequência operacional de 6.78 MHz e potência de saída de 39.3 W.

Abstract: This paper presents a design method of a two-hop wireless power transfer (WPT) system for installing on a robot arm. The class-E inverter and the class-D rectifier are used on the transmission and receiving sides, respectively, in the proposed WPT system. Analytical equations for the proposed WPT system are derived as functions of the geometrical and physical parameters of the coils, such as the outer diameter and height of the coils, winding-wire diameter, and number of turns. Using the analytical equations, we can optimize the WPT system to obtain the design values with the theoretically highest power-delivery efficiency under the size limitation of the robot arm. The circuit experiments are in quantitative agreement with the theoretical predictions obtained from the analysis, indicating the validity of the analysis and design method. The experimental prototype achieved 83.6% power-delivery efficiency at 6.78MHz operating frequency and 39.3W output power.
