It includes high power high voltage constant-current-charging system, capacitors bank, discharge control system, power supply of preignition for Xe-flashlamps, general control and diagnostic system. The power conditioning system drives flashlamps that pump the SSHCL. Flashlamps are driven by high voltage Silicon Controlled Rectifiers switched, resonant charged, discharge pulse forming network. The system uses microchip and digital circle which is based on CAN-bus for control and diagnostics. Energy diagnosis and thermal management are controlled by computers.

其中大功率高压恒流充电装置采用了L-C串联谐振电路，充电功率大，效率较高；储能装置采用了多节脉冲成形网络，可产生波形良好的强电流放电脉冲；放电控制装置采用高压大功率晶闸管，开关速度快，工作稳定；预燃与触发装置采用了开关电源电路，效率高、功耗小；总控与测量装置采用基于CAN总线的数字电路和单片机技术，控制冷却系统在激光器出光时对脉冲氙灯进行水冷，并对全系统进行控制和状态检测，同时具有过压、过流、过热等保护功能。

The transfer function of the LLC resonant converter can be obtained by using the circuit impedance, ratio of resonant inductance, and quality factor. With proper selection of the resonant tank and modulation of the operation switching frequency, the proposed circuit can achieve zero voltage switching, stabilize the output voltage, and then reduce the switching loss.

其后级之半桥LLC谐振式转换器藉由推导电路阻抗、谐振电感比例值与品质因数得到转移函数，以及利用适当的谐振电路的设计与切换频率的调变的方式达到输出电压稳定，并且令功率开关具有零电压切换之功用，以降低功率开关的切换损失。

As to monitoring the signal of exchanging position status of HVS, the thesis adopts the method of gaining the information from relay or assistant contact of switchgear.

对于高压开关设备的位置状态信号的监测采用了从开关设备辅助触点或信号继电器引出接点的方法。

Therefore, when the RESET switch can not be easily pressed, we must be carefully examined, it is best to replace the RESET button on the new switch or button on the external chassis lubrication for fuel processing.

所以，当RESET开关不能按动自如时，我们一定要仔细检查，最好更换新的RESET按钮开关或对机箱的外部按钮进行加油润滑处理。

The proposed T-type reset switch avoids the leakage current influence effectively during the integrating period.

所提出的T型复位开关有效避免了积分期间复位开关漏电流的影响。

There is also a situation because of the RESET switch chassis welding wire in the spin-off too much insulation, coupled with repeated use will cause a RESET switch devanning lines arising from the collision nearly led to automatically restart host.

还有一种情况，是因为机箱内的RESET开关引线在焊接时绝缘层剥离过多，再加上使用过程中多次拆箱就会造成RESET开关线距离过近而引起碰撞，导致主机自动重启。

The switching operation of the switch is completed under the occurrence of resonance condition.

充电器中主开关在零电压时导通而升压二极体在零电流时截止，开关的切换动作是利用共振时完成。
