Experimental investigation of pulse generator based on electromagnetic induction

To verify the feasibility of a pulse generator based on electromagnetic induction, a test model of the small pulse generator was designed. The phase transition of magnetic core was analyzed and the magnetic field was calculated. The equivalent circuit model of the generator was established to get the relationship between electric components. The entire outer diameter of the generator is about 70 mm, and the length is about 85 mm. The diameter of the magnetic core in the generator is 25 mm, and the length is 25 mm. The thickness of the permanent magnet which provides the initial magnetic field is 10 mm. A pulse voltage with a peak value of 784.5 V obtained in the experiment is in agreement with the value of the pulse voltage by calculation.
