Experimental study on magnetizing property of magnetic core for LTD

  • Publish Date: 2007-06-15
  • This paper studies the pulsed magnetizing property of annealing metglass and silicon steel core with polymer foil between layers fitted to the linear transformer driver(LTD). The capacitor fast discharge method was used to acquire a pulse with about 20 ns rise time and mearsure the magnetizing properties of annealing metglass 2605SA1 and silicon sted DG6. Through measuring primary current and secondary coil opened voltage, magnetic core hysteresis loops have been drawn. After the experiment, relative permeability was obtained in different dB/dt. The results indicate that the relative permeability is decreased with the increase of dB/dt. The relative permeability of annealing metglas 2605SA1 is less than 1 000 when dB/dt is more than 20 T/ms and that of silicon steel DG6 is less than 1 000
