Transient electromagnetic transmitter is a part of the transient electromagnetic detection system. In the aspect of short turn-off time for high-power current, there are still many problems to be solved urgently. This paper put forward a design scheme of transient electromagnetic transmitter, amplified the control signal with triode, and put forward a kind of passive constant voltage clamping absorbing circuit, which made the turn-off time shorter and the linearity of the emission currents lagging edge higher. This transient electromagnetic transmitter system is portable and easy to operate. Through experiments we can prove that the transmitter has the characteristic of short turn-off time and high reliability, and it has reached the requirements of field application.
