Description

technical field [0001] The invention belongs to the field of high-voltage electrical appliances, and more specifically relates to an inductor used for current formation in a high-voltage impact circuit. Background technique [0002] The impact of high current has a wide range of applications in high-voltage electrical appliances. For example, the application of pulse current sintering, pulse current electrolytic machining, and some special testing occasions. The pulse inductor plays the role of inductance damping in the shocking large current discharge circuit, and can convert electric energy into magnetic field energy at the moment of flow, and play the role of adjusting the current waveform. [0003] Inductors, capacitors, and switches are the main components in the process of forming large inrush currents, and the output parameters of large inrush currents can be changed by adjusting component parameters. For example, in a high-power pulse power supply, the inductor is ...
