“…On the switch performance, magnetic switch can overcome the shortcomings of other high power switch, which can improve the discharge frequency due to non‐contact closing action and strong repeatability. Magnetic switch can greatly improve the performance of pulse forming unit because of its long service life, high voltage and high resistance to flow [4–8]. In recent years, with pulse power technology application in the military and civilian becomes more and more widely, the research also is more and more urgent, especially in the research of miniaturisation and compactness.…”
