Design of magnetic switch based on metglas magnetic core

A theoretical analysis of the working mechanism and process has been presented for a magnetic switch based on metglas magnetic core. The volume of the magnetic core and the condition for multiple stage magnetic pulse compression circuit were deduced. Then the working process of the magnetic switch was simulated by Pspice. For validation a magnetic switch with 10 kV output voltage and 8.3 compression ratio was designed according to the theoretical analysis and simulation result. The experimental results reveal that the 10 kV, 9.2 μs electric pulse is compressed to 10 kV, 1.3 μs, which is in agreement with the theoretical design. At last, a novel testing method for the hysteresis loop of the magnetic core has been proposed according to this experimental platform. And the hysteresis loop o
