50 kV 全数字化电子枪高压电源设计

摘要

The design of full digital electronic gun high voltage power supply based on DSP was introduced in this paper . This power supply has innovations of full digital feedback circuit and PID closed-loop control mode .The application of high frequency resonant converter circuit reduces the size of the resonant element and transformer .T he current-coupling distributed high voltage transformer and rectifier circuit were employed in this power supply .By this way , the power supply efficiency is improved and the number of distributed parameters is reduced ,and the rectifier circuit could work under the oil-free environment . This power supply has been used in electronic grid-control high voltage system of the irradiation accelerator .%本文介绍了一种基于DSP的全数字化电子枪高压电源，该电源的特点是采用全数字化反馈电路、通过P ID算法实现闭环控制。采用频率较高的谐振逆变电路，减小了谐振元件、变压器的体积。电源因采用电流耦合型分布式高压变压器及整流电路，提高了效率、减少了分布参数及可使高压整流电路工作在无油的环境中。该电源已成功用于辐照加速器电子枪栅控高压电源系统中。
