Description

Technical Field

[0001] The utility model relates to the field of pulse power technology and intelligent manufacturing technology, and in particular to a discharge switch device for performing forward compression and backward interception on pulses. Background Art

[0002] Pulsed power technology, which uses pulsed signals to provide transient high-power output, is widely used in scientific research and medical applications. High-voltage sub-nanosecond pulses, in particular, have been widely used in recent years in tumor cell therapy, metal processing, and environmental management due to their ultra-narrow pulse width, leading and trailing edges (less than 1 nanosecond), and high pulse amplitudes exceeding hundreds of kilovolts.

[0003] Currently, there are three main ways to generate high-voltage sub-nanosecond pulses: compressing the pulse width with the help of a dedicated formation circuit, sharpening and clipping the leading edge of the output pulse formed by a discharger, and discharge structures based on sub-nanosecond fast switches or semiconductor switches.

[0004] Sub-nanosecond pulses generated by semiconductor switches typically have output amplitudes less than 100kV. Therefore, the current realization of high-power, high-amplitude sub-nanosecond pulses still relies heavily on traditional methods of pulse truncation and compression. Compared to methods that use specialized circuits to compress pulse width, pulse sharpening and clipping offer advantages such as more stable waveforms, smaller size, and greater convenience.

[0005] However, waveform capture is not ideal in specialized processing scenarios and cutting-edge biomedical applications. Therefore, to ensure high-amplitude, narrow-width pulses, a switch structure is needed that can shrink the leading edge and truncate the trailing edge of an existing pulse, generating pulses exceeding hundreds of kilovolts and with sub-nanosecond widths.

This structure can further generate high-amplitude, sub-nanosecond pulse width pulses under existing pulse conditions, which can meet the needs of special processing scenarios and cutting-edge biomedicine.
