| description | A transmission circuit of transient electromagnetic instrument based on FPGA was designed in order to improve measurement accuracy of transient electromagnetic instrument. Drive circuit of the transmission circuit was designed with module EXB841 to drive MOSFET located at up-down side of H-bridge, innovative H-bridge and control strategy realized very short turn-off time for MOSFET, and peak voltage interference was reduced by use of RCD protect circuit to improve output signal waves of the transmission circuit. The experiment results show that overvoltage of emission signal of the transient electromagnetic transmission circuit is only 1.33 times of the normal voltage, and the time for oscillating and falling edge are 500 ns and 700 ns, separately, which can realize fast turn-off and has good stability. |
