For high-power shortwave transmitters, it is an indispensable instrument for the exploration of artificial field source electromagnetic method. The main exploration method is to use the earthed electrodes to launch and use the effective electromagnetic field obtained. In order to obtain different levels of signal power, its transmitter requirements, it must have a high voltage, high current, high precision to ensure stable output, but also must have small size, low quality features. In order to promote the transmission and emission of high-power shortwave transmitters in the field of broadcasting industry in our country, it must be explored in depth. On the basis of scientific research projects, switching power supply technology as a starting point for highvoltage high-power electromagnetic transmitter road structure, system modeling programs and system control methods, as China＇s high-voltage high-power electromagnetic transmitter power supply technology is better Lay the foundation for the development.
