Abstract

a presente invenção refere-se a um transmissor de energia (101) para um sistema de transferência de energia sem fio que compreende uma bobina transmissora (103) e um acionador (201) que geram um sinal de acionamento para a bobina transmissora (103) empregando um período de tempo repetitivo com um intervalo de tempo de transferência de energia e um intervalo de tempo de detecção de objeto estranho. um gerador de teste (211) gera um sinal de acionamento de teste para uma bobina de teste (209) durante o intervalo de tempo de detecção de objeto estranho. um detector de objeto estranho (207) executa um teste de detecção de objeto estranho com base em um parâmetro medido para o sinal de acionamento de teste. antes de entrar em uma fase de transferência de energia, um adaptador (213) controla o transmissor de energia (101) para operar em um modo de inicialização de detecção de objeto estranho no qual um valor preferencial de um parâmetro de sinal para o sinal de acionamento de teste é determinado em resposta a ao menos uma primeira mensagem recebida do receptor de energia (105). durante o intervalo de tempo de detecção de objeto estranho, o parâmetro de sinal é ajustado ao valor preferencial.
