The working principle of the pulse power device is: firstly, the required primary pulse waveform (millisecond to microsecond level) is generated by the initial energy storage technology (capacitor energy storage, inductive energy storage, chemical energy, etc.), and then the pulse is used to form the line and switch The technology compresses on the time scale, and the pulse width is grea...

AI Technical Summary

Problems solved by technology

This type of device (Liu Xisan, High Power Pulse Technology, National Defense Industry Press, pages 424-436) needs to use primary power supply, first-level pulse compression, and second-level pulse compression to obtain the required square wave pulse. The disadvantage lies in energy storage The system and the pulse forming system are independent structures, the energy conversion efficiency is low, the system is bulky, and the weight is heavy

The main reasons restricting the practical application of pulsed power sources are large size and high cost. The traditional pulsed power technology can no longer meet the current requirements for miniaturization, light weight and low cost of pulsed power sources.
