摘　　要：设计两种将星上计算机控制器指令信号输出端与部件输入端连接的接口电路.它能抵抗从计算机控制器指令信号输出端发出的宽脉冲干扰,并能将控制器指令信号变换为部件所需的驱动信号.文中给出一些解析结果,可用来根据抗干扰要求和驱动要求计算接口电路中各主要元器件的参数值.Two kinds of interface circuits to interface the output terminator of the computer controller with the input terminator of a component in a spacecraft are designed in this paper. The circuits possess the function of anti-interference wide impulse and convert the computer controller signal to the driving current required by the component. Some detailed analytical results derived from this paper can be used to calculate parameter values of main elements in the circuits according to the requirements for anti-interference and driving.
