| Abstract |
The paper considers Generator of the Spatial
Magnetic Field for medical specific (magnetic field therapy)
purposes. One of essential blocks there is three-channel quasi –
linear power electronics source and set of space oriented
electromagnets. The control module utilizes microcomputer with
floating point digital signal processor (Analog Devices, ADSP-
21364, SHARCTM family). This microcomputer has been
integrated with industrial PC – part of generator, on base of
dedicated PCI Card. The execution block utilizes set of power
electronics inverters based on MITSUBISHI IGBT Intelligent
Power Modules. The project has been realized within two stages.
At first of them a generator in one–channel version for
evaluation purposes has been worked out. Next one has been
dedicated to developing generator in three-channel version. This
paper describes fundamentals of current source control
algorithms and laboratory investigations of generator in one–
channel version. Then, some features of generator in threechannel
version are introduced.
