要約(Abstract) :A low inductance circuit has been fabricated in order to obtain shorter time to saturation during core unsaturation and current pulses with shorter widths during core saturation. B-H curves have been derived from the measured voltage and current waveforms. Characteristics of the magnetic core for pulsed-power generators have been investigated and the Electromagnetic Transient Program (EMTP) simulation has been carried out in order to determine the effects of leakage current on the energy efficiency of a 3-staged magnetic pulse compressor (MPC). As results, the derived B-H curves show the following characteristics: a high ratio of unsaturated to saturated permeability (μun/μsat), a maximum flux swing of about 2.55 T, a high ratio of remanent flux density to saturation magnetic flux density (Br/Bs) and low core loss. And, it is found that μun increases with time to saturation and that μsat is strongly influenced by the stray inductances of the core. By applying custom characteristics to each stage in EMTP simulation, more practical energy transfer in MPC is obtained.
