Research on multi-excitation pulsed airborne electromagnetic Transmitter

摘要

Aero-electromagnetic (AEM) is a geophysical exploration technology that uses aircraft platform to carry electromagnetic exploration equipment, which has the advantages of wide detection range, high efficiency and economy. In this paper, the design and modal analysis of the main circuit topologies, such as the aviation electromagnetic multi-pulse transmitting circuit with large magnetic moment and the phase-shifting full-bridge soft switching circuit, are carried out to improve the power density and transmitting power of the transmitting system, realize the multi-pulse transmitting with large magnetic moment, and effectively improve the detection depth and accuracy.
