Research on the Waveform Synthesis of Electromagnetic Detection Inverter Based on FPGA

Abstract:

Complex geological conditions and limited launch frequencies are the problems which the geological electromagnetic detection faced in our country. In this paper, we designed two FPGA-based detection of electromagnetic emission source inverter control circuits, one is using a phase-shift and complementary drive signal to expand the load range of electromagnetic emission system; the other one is using waveform synthesis technology to achieve that multiple frequencies could launch at one-time, and this method improves the detection accuracy. Both the two control circuits have a positive role in promoting the performance of electromagnetic detection equipment the development of Geological Survey in China.
