一种瞬变电磁发射机阻尼匹配装置及方法
摘要：
本申请公开了一种瞬变电磁发射机阻尼匹配装置及方法，包括阻尼调节模块和控制模块；其中，阻尼调节模块的第一端连接发射线圈的第一输出端，阻尼调节模块的第二端连接发射线圈的第二输出端，阻尼调节模块的控制端连接控制模块的输出端；阻尼调节模块，用于利用控制模块输出的控制信号调节阻尼电阻阻值。本申请在瞬变电磁发射机的发射线圈的第一输出端和第二输出端之间串联有接受控制模块控制的阻尼调节模块，实现在更换发射线圈后，阻尼调节模块能够依据控制模块发送的控制信号调节自身的阻尼电阻，使阻尼电阻与当前发射线圈匹配，能够更好地吸收发射线圈的两个输出端之间的电流过冲和震荡。
摘要（英）：

The present invention discloses a damping matching device and method for a transient electromagnetic transmitter. The device includes a damping adjustment module and a control module; the first end ofthe damping adjustment module is connected with the first output end of a transmitting coil; the second end of the damping adjustment module is connected with the second output end of the transmitting coil; the control end of the damping adjustment module is connected with the output end of the control module; and the damping adjustment module is used for adjusting the resistance values of damping resistors by using control signals output by the control module. According to the damping matching device and method for the transient electromagnetic transmitter of the present invention, the damping adjustment module controlled by the control module is connected in series between the first output end and the second output end of the transmitting coil of the transient electromagnetic transmitter, and therefore, the damping adjustment module can adjust the damping resistors of the damping adjustment module itself according to the control signals sent by the control modules after the transmitting coil is replaced, and therefore, the damping resistors can be matched with a current transmitting coil, and current overshoot and oscillation between the two output ends of the transmitting coilcan be well absorbed.
