1、 Introduction

Electron linear accelerator, as an important particle acceleration device, plays an important role in scientific research, medical diagnosis, industrial applications, and other fields. With the continuous development of technology, the performance requirements for electronic linear accelerators are also increasing, especially in terms of pulse power and charging efficiency. Therefore, designing and implementing an efficient and stable series resonant charging power supply has become one of the current research hotspots. This article will provide a detailed introduction to the design and implementation of a series resonant charging power supply for electronic linear accelerators.


2、 The basic principle of series resonant charging power supply

Series resonant charging power supply is a charging power supply based on the principle of LC resonant circuit. During the charging process, the power supply is connected to the resonant circuit through a switch. When the switch is turned on, the power supply provides energy to the resonant circuit, causing the capacitor and inductor to oscillate. When the resonant frequency of capacitors and inductors matches the frequency of the input signal, the energy transfer efficiency is highest, achieving efficient energy transfer and storage. Finally, when the capacitor charges to the required voltage, the charging process stops. By adjusting the switch state of the power supply and the frequency and parameters of the resonant circuit, effective energy transfer and charging can be achieved.
