Abstract:The magnetic switch is important for solid-state high power pulse modulators due to its excellent characteristics, such as long lifetime, high stability and high power capacity. Some applications require the synchronization of multiple pulse generators, for example, to obtain higher load power. Magnetic coupling is a simple, passive, maintenance-free technique, which can be utilized to reduce the output timing variations of magnetic switched pulse generators. In this paper, a synchronization experiment of two magnetic switches is carried out. The experimental results show that the time difference between the two pulses is reduced from 2.2 μs and 0.6 μs to 0.3 μs and 0.1 μs respectively after coupling the magnetic switches, which demonstrate that the magnetic coupling technique can make magnetic switches operate synchronously. An improved circuit model based on the gyrator-capacitor approach is established which can effectively simulate the synchronization process of magnetic switches. Analysis about the synchronization mechanism is also given.
