Description

technical field [0001] The invention relates to the technical field of pulse generation, in particular to a rectangular pulse generator. Background technique [0002] A rectangular nanosecond pulse is an electromagnetic signal whose output waveform is nanoseconds in duration and has a flat top. The characteristics of rectangular nanosecond pulses are characterized by parameters such as pulse front and rear edge times, pulse half-width, squareness, and pulse repetition frequency. With the development of fine processing such as micro-electrochemical processing and electric discharge processing, super radiation and lasers, a large number of application requirements for pulsed rectangular nanosecond pulses have emerged, and they are developing in the direction of high repetition frequency and narrow pulse width. Rectangular pulses can be generated through a pulse forming network (PFN) or a transmission line, but it is difficult for FPN to generate rectangular pulses with a band...

Problems solved by technology

The rectangular waveforms generated by these two methods are difficult to reach a good value in terms of efficiency, distribution parameter control and structure.

For the single wire, under the same power supply, the output voltage power is lower than that of the double wire; while the structure of the double wire makes it difficult to control the distributed parameters, and the narrower the pulse, the worse the waveform characteristics; A set of switches, while requiring complex matching lines, so the system structure is complex
