Description

technical field [0001] The invention relates to a pulse power source, in particular to a continuous high-repetition-frequency high-voltage pulse source. Background technique [0002] Traditionally, pulsed power technology has served the field of national defense scientific research, generally in a single operation. With the increasing demand in military and high-energy physics fields, and the application of pulse power technology in medical, industrial, civil and other fields, the new demand for a certain average power makes the pulse source must work at a repetition rate. The research of a new generation of pulse sources is not blindly pursuing the high power or fast rising edge of a single pulse, but more attention is paid to pulse sources with higher repetition frequency, accuracy, controllability and flexibility under a certain pulse power output. Taking into account the reliability, volume, cost and other factors of the pulse source. At present, the pulse source techn...

Problems solved by technology

However, when multiple MOSFET devices are connected in series and parallel to meet the voltage and power requirements, as a three-terminal device, MOSFETs require complex circuits to provide trigger signals, which increases equipment costs and brings difficulties to use and maintenance.

The issue of trigger synchronization involved in increasing monopulse power is more complex

In addition, the turn-on time of tens of nanoseconds is still relatively long. Under the condition that ps-level short pulse applications are becoming more and more common, this indicator has become an obstacle for the application of MOSFETs in the fields of ultra-wideband radar, communication and solid-state lasers.
