Abstract

The invention discloses a combined pulse formation network and a method. The combined pulse formation network mainly comprises a pulse formation line, an energy-storage capacitor, a switch and a pulse transmission line, wherein the connecting relationship thereof is as follows: the output end of the pulse formation line is respectively connected with the high voltage end of the energy-storage capacitor and the anode of the switch; the low voltage of the energy-storage capacitor is grounded; and the cathode of the switch is connected with the input end of the pulse transmission line. The combined pulse formation network can be matched with a variable resistance load, supplies a short pulse high voltage for the load impendence to puncture when the load impedance is high, and supplies a subsequent long pulse for finishing the specific physical machining or chemical reaction on the load when the impedance becomes low. Compared with the conventional high voltage pulse power supply used in the variable impedance load, the combined pulse formation network greatly increases the utilization rate of energy and prolongs the service life of the power supply.

Description

technical field [0001] The invention belongs to the technical field of pulse power, and in particular relates to a combination pulse forming network. Background technique [0002] High-power pulse technology is realized by rapidly compressing, converting or directly outputting the "slow" stored energy with higher density from space and time to the load. In the past 50 years, the rapid development of high-power pulse technology has attracted attention. At present, it has been able to generate tens of megaelectron volts and high-current electron beams and ion beams up to several megaamperes in a very short period of time. The basic principle of the large-scale pulse power system currently used is to first generate a high-voltage slow pulse with a voltage rise time of the order of microseconds, and then convert it into a high-voltage and high-power fast pulse by the power forming system (the voltage rise time is generally in the order of microseconds) nanoseconds).
