The Magnetic Pulse Compressor (in the following MPC) is a device that is capable of creating high current and high voltage impulses. In some circumstances, it is operated more cost effectively and reliably than the impulse generators made of semiconductor elements and it is more precisely controlled than the spark gap devices designed by Marx. The main disadvantages of the MPC are the sensibility to magnetic effects and the difficult construction and design of the non-linear magnetic switching element. The first device was developed in 1951 and it was used for a radar power supply but at that time the technical conditions were not enough advanced to create a high-precision and high-efficiency magnetic core so the MPC technology was abandoned, the impulse generators based on semiconductor devices and spark gaps have become commonly used. Nowadays the new technological improvement in magnetic and semiconductor technology allows to create high-efficiency and high-impulse-rate Magnetic Pulse Compressors.

In my work I study the principal of operation of the MPC and investigate the application possibilities in the High Voltage Laboratory.
