Dynamic characteristics of magnetic switch with pulse compression circuit

On the basis of one-order magnetic pulse compression (MPC) circuit, this paper puts forward a method for measuring the dynamic magnetic properies of magnetic cores in actual working conditions, such as hysteresis loop and saturated permeability, to guide the design of magnetic switches in the MPC experiments. Widely used amorphous magnetic cores and nanocrystalline magnetic cores are chosen, and their dynamic magnetic parameters are obtained. The magnetic switch using domestic amorphous magnetic core, outputs pulses of 73 ns risetime, 28.3 kV peak voltage, and 503 ns full width at half maximum. The magnetic switch using Japanese nanocrystalline magnetic core outputs pulses of 30 ns risetime, 28.4 kV peak voltage, and 193 ns full width at half maximum.
