The invention discloses a magnetic core accurate replacement system of a high-repetition-rate magnetic pulse compression network. The magnetic core accurate replacement system comprises a direct current switch power supply, an isolation inductor L1, a current-limiting resistor, an absorption capacitor, an absorption resistor, an absorption diode, an isolation inductor L2 and a replacement winding, wherein the direct current power supply is connected with the absorption capacitor through the isolation inductor L1 and the current-limiting resistor, and is connected with the replacement winding through the isolation inductor L2; after the absorption resistor and the absorption diode are connected in series, the two are connected with two ends of the capacitor in parallel; an anode of the absorption diode and the absorption resistor are connected in series; a low-voltage end of the absorption capacitor is connected with the ground; and the replacement winding is independently connected with a magnetic switch. A quasi-molecule excitation power supply system of a multi-pole magnetic pulse compression switch is suitable for being adopted by the magnetic core accurate replacement system, the problem of quick replacement of a magnetic core in a high-repetition-rate magnetic pulse compression system can be well solved, so that the magnetic pulse compression system can normally and reliably run.
Description
Technical field [0001] The invention relates to a magnetic core accurate reset system for a magnetic pulse compression network, specifically a magnetic core reset device for a pulse gas laser magnetic pulse compression network such as a high repetition rate excimer, and is especially suitable for a magnetic pulse compression network at a KHz level high repetition frequency The core is accurately reset. Background technique [0002] In 1951, British Melville was inspired by the phenomenon that the impedance drops rapidly after the inductor is saturated, and proposed the use of magnetic switches to generate high-power fast pulses, and then extensive research on the application of magnetic switches abroad. Domestic research on magnetic switches is mainly focused on high-voltage dust removal equipment, accelerator systems, radar systems and prolonging the life of thyristors in laser fast discharge. The current high-repetition rate excimer laser uses semiconductor solid-state switche...
