摘要
The Principle and structure of a transmitter based on CSAMT with excitation control is introduced.In particular,the main modules of the transmitter are illustrated clearly.Strong expandability of power is the greatest advantage of this system.At present,the transmitting power is above 30 KW in laboratory experiments.Transmitter of 850V/25A has been well implemented in the field work.Great simplicity in electrical circuit structure,easy maintenance and high stability are the most remarkable characteristics of this system.The study has provided an effective solution for the development of other high-power active electromagnetic prospecting transmitter.
