Study on electromagnetic detection transmitter system

The limited transmitting frequency and the adaptability of geological conditions are the main problems which the geological electromagnetic detection faced in our country. To obtain more parameters at the same power supply and improve the detection of depth and efficiency, the power supply technology of multi-frequency and a constant amplitude is developed and applied, meanwhile, this paper introduces the basic principles of transmission systems and the design of waveform synthesis unit, main circuit, isolated driver unit, the buffer unit and the control systems, ultimately the experiments prove the transmitter we designed has the excellent characteristic which has super wideband and wide range of load regulating. The design of transmitting is reasonable, the system designed has the stable and reliable performances. The whole design and experiments play a promoting role in the development of electromagnetic detection technology.
