Title
10-MHz High-Power Pulse Generator on Boost Module
Abstract
Nanosecond pulse output at megahertz level is wide interest because of its potential application in the experiment of cell function electric field regulation and accelerator electron gun injector. In this article, a pulse generator based on the combination of the Blumlein pulse forming line and the boost method is proposed. Different from the traditional Blumlein line, in this module, the RLC circuit is used to improve the pulse voltage amplitude and energy conversion efficiency. According to the different inductance values, the generator has two working modes: discontinuous and continuous with different output characteristics. RF-Si-mosfet is used as the main switch and used dual-switch timing logic control to adjust the output waveform parameters. It can obtain the output pulse frequency two times the switching frequency, effectively reducing the single switching loss. By constructing a prototype, the pulsewidth of 5 ns, maximum repetition of 10 MHz and 2.5-kW peak power is realized. In addition, a dc equivalent pulse method is proposed, which is suitable for the thermal simulation of switching at high frequency and gives the heat dissipation measures. The effectiveness is verified by simulation and experiment.
