Multifunctional pulse-magnetic installation with variable shape and parameters of the discharge current

The paper considers methods and circuitry for creating a multifunctional pulse-magnetic installation with variable parameters of the discharge current for forming of pulsed magnetic fields. The installation is designed to conduct comprehensive research on the effect of the magnetic field on various materials in mechanical engineering, medicine, pharmacology and plant growing. Currently, traditional designs of the installations operate in a single-discharge mode and generate oscillatory shaped pulses of current in the form of a damped sinusoid. The developed installation with power intensity of 5 kJ operates in four modes: oscillatory discharge of one energy storage device with a high frequency of the discharge current, synchronous discharge of two energy storage devices, asynchronous discharge of two storage devices with an adjustable delay relative to each other, and in the mode of forming a mono-pulse with a cutoff of the current of subsequent half-cycles. The paper presents the block diagram of the multifunctional pulse-magnetic installation (PMI), provides recommendations on the selection of the main components when creating specialized installations for solving specific tasks. The results of testing the PMI are given.
