Abstract

The paper considers Generator of Spatial Magnetic Field for medicine purposes - magneto therapy. One of essential blocks there is a precision three-channel power electronics current source, powering set of space oriented induction coils (electromagnets) - sources of a magnetic field. The control module utilizes DSP based microcomputer for power electronics applications. The microcomputer is implemented at PCI card, which is integrated with industrial PC. The execution block of current source utilizes IGBT/IPM based power electronics inverter working in PWM mode. The paper describes fundamentals of current source control algorithms and selected test results of laboratory prototype of generator.
