| 摘 要： | 瞬变电磁法的发射波形对勘探结果起着重要的作用，由于现有瞬变电磁法的发射机所用整流逆变电路存在着一些不足，当发射机工作一段时间后的内部电压会随之下降，使发射波形产生畸变，导致测量结果不准确。针对这些问题，基于三相PWM整流电路在原有电路的基础上进行改进，这样既可以提高直流侧电流电压的稳定性，又可以提高电路的功率因数，同时在逆变部分加上滤波电容，滤除谐波，保证输出电流波形的质量，从而提高测量的准确度。并且在MATLAB／Simulink中进行仿真实验，验证其可行性，并且得出瞬变电磁法所需要的波形。 |

| Abstract: | The emission waveform of the transient electromagnetic method has an important influence on the results of exploration. According to these disadvantages, improving the original circuit, three-phase PWM rectifier circuit take the place of the original three-phase controlled rectifying circuit. This can improve the stability of DC current and voltage and power factor. And add filter capacitance on the inverter part to filter harmonic wave, ensuring the quality of the output current waveform so as to improve the accuracy of the measurement. Simulation experiment in MATLAB/Simulink and draw the waveform figure of the transient electromagnetic method. |
