Design of a fast, high power magnetic generator for the stimulation of living tissues: A biomedical engineering application of electromagnetism and power electronics

摘要

This paper relates to the design and realisation of a high power (6000 A, 650 V) magnetic generator delivering ultra short (340 us) high intensity (2 T) pulses. More than ten years of technical collaboration between two important graduate engineering schools of Bordeaux were necessary to carry out this project. This practical realisation was supported perfectly by the power electronics, electromagnetism and microprocessor courses given at ENSCPB and ENSEIRB graduate engineering schools. In the first place, we explain the educational interests of this realisation. Then, we give a detailed description of the system, including the tests which were used to check the specifications. Finally we conclude on possible uses of our equipment in biomedical research. As an illustration of bio medical applications, our apparatus was used for tests on living tissues (animal, bacteria, etc).
