摘要

摘要: LC谐振充电是Tesla变压器常用的初级电容充电技术，但存在对控制时序要求高、易受电磁干扰和不具备故障保护能力等缺陷。针对这个问题，提出了一种时基反馈控制的LC谐振充电电源。该电源与传统LC谐振电源的主要区别在于，采用特殊设计的时基反馈电路取代多路时基控制器，将能量回收开关反向阻断瞬间的电压突变调制为谐振晶闸管触发信号，从而在能量回收结束时刻启动谐振充电，实现各工作回路准确按照预定时序运行。时基反馈电路由高压元件构成，不易受电磁干扰，且在原理上具备负载短路保护能力。该技术已经应用于CKP1000，CKP5000等多台Tesla型超宽谱脉冲源。实验结果表明，在强脉冲辐射环境下，该电源能够1000 Hz重频稳定运行，且能够在Tesla变压器初级短路故障时进行快速自动保护。

Abstract: This paper presents a time-base feedback controlled LC resonance capacity charging power supply (CCPS) for Tesla transformer.The main improvement of this new type of LC resonance CCPS is that the multiplex pulse generator used to trigger resonance charging process in traditional LC resonance CCPS is replaced by a feedback circuit specially designed to offer appropriate time-delay triggering.The feedback circuit, composed of several high voltage components, has efficient immunity to electromagnetic interference.Meanwhile, the output short-circuit protection capability of the feedback circuit is available in principle.This new LC resonance CCPS is applied in several Tesla-type ultra wideband (UWB) pulse generators such as CKP1000 and CKP5000, etc.Experimental results show that the new LC resonance CCPS can operate stably in intense radiation circumstance with a repetition rate of 1000 Hz and has quick response to failure occurred in primary circuit of Tesla transformer.
