Abstract

"DISPOSITIVO DE CONTROLE DE SUPRIMENTO DE ENERGIA E MéTODO DE CONTROLE DO MESMO". Quando o fornecimento de energia a partir de uma fonte de alimentação 101 a uma carga 102 é controlado de um modo comutante por um comutador semicondutor QA, um meio de geração de tensão de referência (Qb, Rr) gera uma tensão de referência (VDSB) que tem uma característica de tensão substancialmente equivalente àquela de uma tensão entre os terminais do comutador semicondutor QA que está conectado a uma carga predeterminada. O meio de detecção* detecta uma diferença entre a tensão (VDSA) entre os terminais do comutador semicondutor QA e a tensão de referência (VDSB). O meio de controle que consiste do circuito de acionamento 111 e CMP1 executa um controle liga/desliga do comutador semicondutor QA de acordo com a diferença entre a tensão (VDSA) entre os terminais do comutador semicondutor e a tensão de referência (VDSB).
