Nanosecond pulse generators based on magnetic pulse compression system

Magnetic pulse compression (MPC) system has been widely-used for over a few decades as a technique for producing short-duration, high-peak-power pulses reliably. A novel MPC system which does not contain external demagnetization circuits, has broadened the application of MPC systems. Improvements for novel MPC systems are presented. To meet the required voltage and compression gain and on considering of the overall system efficiency, two kinds of most popular MPC systems based on the improved MPC topology are designed, which are 2-stage MPC system and 3-stage MPC system, respectively. Based on the improved MPC topology, several kinds of compact pulse generators are built in pulsed power and supply technology laboratory of Institute of Electrical Engineering, Chinese Academy of Sciences. These generators illustrate that the improved MPC topology, together with solid state switches provides an ideal way to generate pulses of around 100 nano-seconds in width, with mid and high voltage of 10 kV to 100 kV, and a high repetition frequency of about 30 kHz.
