Research on Controlling Method of High-Power Electromagnetic Transmitter Power Supply

Abstract:

High-power electromagnetic transmitter power supply is an important part of deep geophysical exploration equipment, especially in complex environments, where how to control the high accuracy and stable output of the power supply as well as the redundancy safety of the system become the key issue in its designing. A triple-loop control including inner current loop, outer voltage loop and load current forward feedback and a digitalized voltage/current sharing control method are proposed for the realization of the rapid, stable and highly accurate output of the system. System simulation and field geological exploration experiments demonstrate the effectiveness of the control method which could ensure both the systems excellent stability and the outputs accuracy.
