沿着带反馈环路的传输线的电源调节
摘要：
一种用于对提供给传输线系统的电压加以控制的系统(150)。所述系统(150)包括一个traA系统(150)，用于对提供给传输线系统的电压进行控制。系统(150)包括一条具有特性阻抗和连接在其末端的负载阻抗的传输电缆(134)。电源(154)被连接到传输电缆(134)。电源(154)被配置成接收电压信号输入(157)并且基于所述输入来驱动一个源电压VS。反馈单元(155)则被配置成接收作为输入的电源电流(IS)，此外还被配置成产生一个随IS变化的反馈电压(VF)。设定电压单元(152)被配置成产生一个基本恒定的电压(Vset)，而加法器(153)则被配置成将所述设定电压(Vset)添加给反馈电压，以便产生向电源(154)提供输入的电压信号(157)。
摘要（英）：

A system (150) for controlling voltage supplied to a transmission line system. System (150) includes a transmission cable (134) having a characteristic impedance and a load impedance connected at its distal end. A power source (154) is connected to transmission cable (134). Power source (154) is configured to receive a voltage signal input (157) and to drive a source voltage VS based thereon. A feedback unit (155) is configured to receive the power source current (IS) as an input and further configured to generate a feedback voltage (VF) that varies with IS. A set voltage unit (152) is configured to produce a substantially constant voltage (Vset) and an adder (153) is configured to add the set voltage (Vset) to the feedback voltage to generate the voltage signal (154) that provides the input to power source (157).
