Embodiment 1
[0057] see Figure 1 to Figure 22 , a high-frequency ultra-short electron gun gate-regulated pulse power supply system for generating voltage-doubling pulses, mainly including a power supply, a control module, a charging inductor L1, a pulse forming line, a MOSFET switch tube M1, a control module and a matching load R1.
[0058] The power supply supplies power for the grid-regulated pulse power supply system of the high-frequency grid-controlled electron gun. The control module controls the on-off sequence of the MOSFET switch tube M1, so that the high-frequency ultra-short electron gun grid-regulated pulse power supply system switches between the LR charging state and the LC oscillation state. When the MOSFET switch tube M1 is turned on each time, the high-frequency extremely short electron gun grid-regulated pulse power supply system works in the LR charging state. MOSFET switch tube M1 conducts each time for t on . When the MOSFET switch tube M1 is turned off each time, ...
