Abstract

1/1 resumo “circuito de fornecimento de energia” problema: para prover um circuito de fornecimento de energia que é usado em um transmissor que realiza comunicação sem fio de banda larga, que aumenta o eficiência de conversão de fornecimento de energia, e com o qual é possível minimizar o tempo de transição de alteração de nível de tensão, bem como melhorar as características de distorção dos sinais de saída. solução: um circuito de fornecimento de energia inclui: uma unidade de amplificador push-pull que amplifica um sinal de entrada com um protocolo de amplificação push-pull; uma unidade de fornecimento de energia variável, que varia, com um sinal de controle, o nível de tensão de uma tensão de fornecimento de energia que é fornecido para o amplificador push-pull; uma unidade de controle de comutação (83') que, com base no sinal de entrada, emite o sinal de controle que controla o nível de tensão da tensão de suprimento de corrente; e uma unidade de controle de temporização (121) que aplica um retardo de tempo específico ao sinal de entrada. quando o sinal de controle se eleva, a unidade de controle de comutação (83') causa com que o sinal de controle se eleve a uma temporização mais rápida, de acordo com a temporização de transição de comutação do nível de tensão, do que um tempo de retardo na unidade de controle de temporização (121), e, quando o sinal de controle cai, a unidade de controle de comutação (83') causa com que o sinal de controle caia na temporização do tempo de retardo.
