Abstract
Background:
Electromagnetic detection is an important method of geophysical exploration.
The transmitting system is an important part of the electromagnetic detection equipment.
Methods:
The general topologies of a transmitting system for EM instrument are analyzed. The
basic principle of EM detection is interpreted. In order to improve the output power and give consideration
to the dynamic performance, an electromagnetic transmitting system based on the tri-state
boost converter is proposed in this paper.
Results:
The principle of the proposed transmitting system is analyzed. The topology of the proposed
transmitting system is illustrated and the working modes of tri-state boost converter are given.
Conclusion:
The simulation model is established and the simulation experiment is carried out to
verify the feasibility of the new electromagnetic transmitting system.
