如图2，软启动电路：高压发生器的主电源回路通电前，需要对整流电路的平滑电容进行充电，通过软启动保护电路来限制充电时的浪涌电流；当主电源电路输入电源类型交流电时，在实用案例中通常为3phase 400VAC+10％/-20％50-60Hz，此时线电压通过率先吸合接触器K2，经软启动电流限制电阻R1、R2、R3供给整流电路，用于后端直流母线平滑电容的充电；再经过直流母线平缓电容预充检测电路的检测，判断直流母线电容充电是否正常，进而通过吸合主电源回路接触器K1，接通主回路线电压至整流电路；当主电源电路输入电源类型为直流电时，在实用案例中根据不同规格高压发生器计算值设定，通常为450～622vDC范围左右，此时通过线电压率先吸合接触器K4，经软启动电流限制电阻R3、R4供给整流电路，用于后端直流母线平滑电容的充电；同样经过直流母线平缓电容预充检测电路的检测，判断直流母线电容充电是否正常，进而通过吸合主回路接触器K3，接通主回路线电压直至逆变电路；

时，则不经过该回路，以保证直接经整流桥导通二极管的减少带来的电流容量不足以支撑后端大功率曝光，以及预充回路元器件耐压寿命，交直流型式不一带来的电磁兼容问题；
检测放电电路：检测电路用于检测上电瞬间对直流母线平滑电容的充电状态；放电电路用于系统断电后将直流母线电容存放的电压通过R13、R14、R15、R16快速释放；
逆变电路：串联谐振型逆变电路由VT1、VT2、VT3、VT4组成，通过反馈二极管D1、D2、D3、D4进行续流，调整功率开关管触发脉冲的频率来调输出功率，用于控制功率的输入和曝光时间；
高压倍增电路:高压倍增电路通常均为单相全桥整流电路，可使用两套高压变压器，阳极和阴极各自一套电路，整流后直流电压串联，用于降低高压元器件的耐压要求；
如图2，一种交直流兼容输入供电高压发生器装置，包括：
软启动电路：高压发生器的主电源回路通电前，需要对整流电路的平滑电容进行充电，通过软启动保护电路来限制充电时的浪涌电流；当主电源电路输入电源类型交流电时，在实用案例中通常为3Phase 400VAC+10％/-20％50-60Hz，此时线电压通过率先吸合接触器K2，经软启动电流限制电阻R1、R2、R3供给整流电路，用于后端直流母线平滑电容的充电；再经过直流母线平缓电容预充检测电路的检测，判断直流母线电容充电是否正常，进而通过吸合主电源回路接触器K1，接通主回路线电压至整流电路；当主电源电路输入电源类型为直流电时，在实用案例中根据不同规格高压发生器计算值设定，通常为450～622vDC范围左右，此时通过线电压率先吸合接触器K4，经软启动电流限制电阻R3、R4供给整流电路，用于后端直流母线平滑电容的充电；同样经过直流母线平缓电容预充检测电路的检测，判断直流母线电容充电是否正常，进而通过吸合主回路接触器K3，接通主回路线电压直至逆变电路。

时，则不经过该回路，以保证直接经整流桥导通二极管的减少带来的电流容量不足以支撑后端大功率曝光，以及预充回路元器件耐压寿命，交直流型式不一带来的电磁兼容问题。
检测放电电路：检测电路用于检测上电瞬间对直流母线平滑电容的充电状态；放电电路用于系统断电后将直流母线电容存放的电压通过R13、R14、R15、R16快速释放。

高压倍增电路:高压倍增电路通常均为单相全桥整流电路，可使用两套高压变压器，阳极和阴极各自一套电路，整流后直流电压串联，用于降低高压元器件的耐压要求。
本发明仅需改动输入端接口电路和控制电路软件，可把主电源输入端子合并在一起，由控制电路自由切换供电回路用于兼容交直流输入，高压发生器结构主电路中整流电路、逆变电路、高压倍增电路部分均无需改动。
如图3，交直流兼容输入高压发生器辅助电源电路包含辅助电源和控制电路，其中常规高压发生器辅助电源通常由开关电源经交流转化为所需直流电用于内部高压发生器控制板卡的供电，通常输入为Single Phase 230VAC+10％/-20％50-60Hz。而开关电源内部结构通常首先通过防雷单元到电磁干扰滤波电路，经过单相整流电路和滤过电路得到干净的直流电，最后经功率转换电路、进一步整流滤波电路，然后将所需低压直流电输出；其辅助电路包含输入过压欠压保护电路、功率因数校正单元、控制器、稳压环电路、输出限流过压保护电路、输出短路保护电路等。本发明点针对采用开关电源的输入单元好坏，在理性情况下，对交流电进行桥式整流转化为直流电时，忽略二极管的压降以及滤波电路的损耗，转化得到的直流电源为交流电有效值的根号2倍，即U＝1.414u，例如～220vAC直接全桥整流电容滤过得到的直流电源为220X1.414＝311vDC，由于整流二极管的压降等，在实际应用中的输出电压会偏低。根据这一特性，只要二极管、电容电阻等耐压寿命值足够，前端保险丝协调保护兼容，对PFC功率因数校正进行适当调整，开关电源既可兼容交直流输入供电。在实用案例中，可选用市面现有开关电源，通常可兼容交流230vAC±20％输入供电和直流

宽范围输入供电。控制电路此处主要针对上述主电源电路回路与外接网电源接通后的预充和限制以及与外接网电源断开后的残余电荷快速释放。
