参阅图 2, 图 2是本发明的控制电源供应的电压和电流的系统的第二实施例的示意说 明图, 是将本发明的控制电源供应的电压和电流的系统和方法应用于通用串行总线的实 施例, 标准的通用串行总线主机只能通过通用串行总线连接器向每一通用串行总线设备 提供的电源的电压只有 5V, 而且最大电流也只有 0. 5A, 向每一通用串行总线设备所提供 的最大功率只有 5V X 0. 5A = 2. 5W, 不足够一般的应用, 所以很多通用串行总线设备都 要另带电源供应装置, 将本发明的控制电源供应的电压和电流的系统和方法应用于通用 串行总线后, 通用串行总线主机向每一通用串行总线设备所提供的最大功率提升至 36V X 1A = 36W, 功率大幅提高 14倍以上, 可足够一般的通用串行总线设备的耗电量, 例如 喷墨打印机、 扫描器、 调制解调器、 网络卡等通用串行总线设备, 采用本发明的控制电 源供应的电压和电流的系统和方法的通用串行总线后, 一般的通用串行总线设备无须另 带电源供应装置, 而且只要一条通用串行总线电缆就可提供电源和数据交换等功能, 可 大幅节省成本。 继续参阅图 2, 图 2的第二实施例与第一 施例相比, 不同之处在于第二实施例出的 系统还包括有连接器(4) 、 电缆 (5) ,
以及,

(4)和电缆(5)上的 D-和 D+接线将该负载电源的负载电源信息传送给电源供应装置(1 ), 然后由电源供应装置 (1 ) 将输出的电源从基本电源改变为负载电源信息内容所指定的电 压及最大供应电流和极性的负载电源, 并通过连接器 (4)和电缆 (5)上的 VBUS和 GND 接线将负载电源传送到电源控制装置(2) , 电源控制装置 (2)检测到电源供应装置(1 ) 输出的负载电源是负载电源信息的内容所指定的电压和极性的电源时, 将电源供应装置
( 1 ) 输出的负载电源传送给用电设备 (3) , 所述的负载电源信息包括电源电压、 电源 的最大供应电流、 电源极性等, 所述的 D-和 D+接线是标准通用串行总线连接器的其中部 份接线的定义。
此外, 在第二实施例中, 所述的电源控制装置 (2) 向用电设备 (3 ) 供应的负载电 源的电压的范围由 5V至 36V, 以及, 所述的电源控制装置 (2) 向用电设备(3)供应的 负载电源的最大电流为 1A。
参阅图 3, 图 3是本发明的控制电源供应的电压和电流的系统的第三实施例的示意说 明图, 与第一实施例相比, 不同之处在于第三实施例中, 电源控制装置 (2) 与电源供应 装置 (1)之间共用同一对接线 P+和 P-传送基本电源、 负载电源、 负载电源信息, 其中, 在电源供应装置 (1 ) 内, 电源调整器(102) 的输出 P+与通讯接口 (103) 的数据线 D+ 相连接, 电源调整器(102) 的输出 P-与通讯接口 (103) 的数据线 D-相连接, 以及, 在 电源控制装置 (2) 内, 电源开关 (202) 的输入 P+与通讯接口 (203) 的数据线 D+相连 接, 电源开关 (202) 的输入 P-与通讯接口 (203) 的数据线 D-相连接。
