Problems solved by technology
Compared with the passive compensation method, the existing passive compensation pulse generator technology has the following defects: the pulse power modulation method is single, and the output power can only be modulated by increasing the phase number of the armature winding or connecting an external capacitor; the power system is large in size and weight, External capacitors and adding windings will inevitably increase the volume and quality of the power supply system, reducing energy density and power density; the application field is limited, and it is difficult to adjust according to the change of load demand due to the difficulty of power modulation. in a specific field

Description
technical field [0001] The invention belongs to the technical field of pulse power sources, and relates to a pulse generator, in particular to a selective passive compensation pulse generator. Background technique [0002] Compensated pulse generator is a pulse power source that uses inertial energy storage. It uses the principle of electromagnetic induction and magnetic flux compression to reduce the inductance of the generator, so that it can output high-amplitude pulse current. The generator integrates energy storage, electromechanical energy conversion and pulse formation, and has the advantages of high energy density and power density, high stability and reliability. Compensation pulse generators can be divided into three categories according to the compensation method: passive, selective passive and active. The active compensation method requires an external compensation current, and the passive compensation method uses an aluminum alloy compensation cylinder to fully...
