摘要: 电磁探测设备是国内外研究的热点.本文通过分析频域电磁探测发射机的拓扑结构,设计了具有上升、下降沿均钳位,且输出电流阶段连接恒流源的发射电路,以及钳位电压源电容、恒流电感值,并建立了系统模型.仿真结果表明,该频域电磁探测发射机能在感性负载较大、发射频率较高的情况下,输出电流幅值大且为常规桥式发射电路3倍,具有交流方波稳定、线性度良好等优点.

Abstract: Electromagnetic detection device is a research focus. In this paper, frequency domain electromagnetic detection transmitter topology structure, designed with up and down along the clamp, and the output current phase connection the launch of constant current source circuit, design of the clamping voltage source capacitance inductance value, constant current, system model is established. The simulation results show that the frequency domain electromagnetic detection emission function under the condition of inductive load is bigger, high firing frequency, output current amplitude, 3 times greater than that of the conventional bridge type transmission circuit. Besides, ac square wave is stable, with good linearity, etc.

Key words: electromagnetic detection machine, high firing frequency, strong stability, study design
