Abstract

"CIRCUITO E MéTODO PARA ECONOMIZAR ENERGIA DE UM MONITOR" Trata-se de um circuito e método para economizar energia de um monitor que é capaz de desligar automaticamente uma alimentação principal do monitor de acordo com uma pluralidade de sinais de controle de DPM, no caso em que um computador não funciona por um período de tempo predeterminado. O circuito inclui: uma peça de alimentação de energia para suprir uma energia de corrente contínua (CC); uma primeira peça de transformação para aplicar a energia de CC para resultar desse modo em uma pluralidade de voltagens diferentes; uma segunda peça de transformação para aplicar a energia de CC para resultar desse modo na alimentação do microcomputador, na potência do aquecedor e na potência de funcionamento da primeira peça da transformação; um microcomputador para determinar um modo normal e um modo de economia de energia de acordo com um sinal de vídeo dos equipamentos conectados ao monitor, para resultar desse modo um sinal de controle; uma primeira peça de economia de energia para controlar o funcionamento da primeira peça de transformação de acordo com o sinal de controle do microcomputador; e uma segunda peça de economia de energia para cortar a potência do aquecedor aplicada pela segunda peça de transformação de acordo com o sinal de controle do microcomputador.
