Abstract

In order to generate the unipolar and bipolar pulsed magnetic fields and improve the energy efficiency of the magnetic field generator, a multi-module energy-saving (MMES) pulsed magnetic field generator is designed. The circuit topology of the MMES pulsed magnetic field generator is presented and the experimental data are measured by experiments. The results show that the peak current values of unipolar and bipolar pulsed magnetic fields are 156 A and 154 A by discharging two capacitors, and the intensities are 87.6 mT and 86.5 mT, respectively. The energy-saving rates of unipolar and bipolar pulsed magnetic fields can be up to 17.64% and 19.36%, respectively. Therefore, it has very high application and research value in the field of biological magnetism therapy.
