Research on Precise Damping Matching for Transient Electromagnetic Transmitter

摘要：

　　A method is introduced to precisely match the damping resistor of different transmitting coils via the output port of the transient electromagnetic transmitter.Theoretical analysis of the distributed parameter model of the transmitting coil are described.Equations calculating the critical damping resistor are derived from the self-inductance, internal resistance, and the distributed capacitance of the transmitting coil, accordingly.Extensive experiments demonstrate that the proposed method can rectify the overshoot and oscillation phenomenon of the emission current during the late period of the turn-off.
