技术领域
本申请涉及脉冲调制器技术领域，特别涉及一种脉冲调制器及其充电方法。
背景技术
近年来，随着加速器技术的不断发展，出现了对于加速器新的工作模式的需求，即期望加速器系统在短时间内大功率工作。最近一大医疗领域的研究热点即超高剂量率放射治疗就需要医用加速器系统工作在瞬时大功率的模式之下，除此之外，对于电子器件的抗辐射研究、快速无损检测的实现以及研制基于加速器的闪光光源都需要加速器系统采用这样的工作模式。
以超高剂量率放射治疗为例，随着医用电子直线加速器系统相关技术的趋于成熟，放射治疗技术的飞速发展在医疗领域备受关注，对于放疗设备的小型化、高剂量等新需求的出现为研究人员带来了新的挑战，也为医用电子直线加速器的发展指明了新的方向。
根据近年的生物学实验结果，有望在不久的将来实现超高剂量率的放射治疗技术。相较于常规的放疗技术，超高剂量率放射治疗技术需将剂量率提高2-3个量级，同时将照射时间缩短至百毫秒量级。
在医用电子直线加速器系统中，三相动力电通过电源系统和控制系统驱动脉冲调制器，脉冲调制器将得到的直流高压转变为大功率脉冲高压供给磁控管/速调管。脉冲调制器主要由高压直流电源单元、MARX发生器、脉冲变压器等组成，其中，高压直流电源单元一般包括三相四线380V调压变压器、高压变压器和高压整流二极管组件。
然而，由于超高剂量率的放射治疗技术的剂量率大大提高且照射时间仅有百毫秒量级，仅使用高压直流电源单元大大提高了对于供电功率的需求。

具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
下面参考附图描述本申请实施例的脉冲调制器及其充电方法。针对上述背景技术中心提到的相关技术中使用高压直流电源单元供电不仅会浪费能源，而且降低效率的问题，本申请提供了一种脉冲调制器，通过设置有至少一个超级电容，并利用至少一个超级电容的短时间、大功率的放电，完成脉冲调制器的供能，进而实现超高剂量率的放射治疗技术，替代了相关技术中的直流电源直接供电方法，降低了供电功率需求。
具体而言，图1为本申请实施例所提供的一种脉冲调制器的方框示意图。
如图1所示，该脉冲调制器10包括：脉冲发生器100、脉冲变压器200和充电单元300。
其中，脉冲发生器100用于生成脉冲高压能量；脉冲变压器200用于基于脉冲高压能量对预设功率源放电，以生成脉冲电压；充电单元300包括至少一个超级电容301，充电单元300在至少一个超级电容301充能以处于预备放电状态后，为脉冲发生器100供电，以利用脉冲变压器100生成脉冲电压。其中，超级电容储能过程可逆，可反复地稳定充放电数十万次，安全可靠。同时，超级电容功率密度高，可作为功率辅助器供给大电流。可选地，在一些实施例中，如图2所示，充电单元300还包括：预充充电电源302和充电电源303。其中，预充充电电源302的输入端与市电供电端相连，预充充电电源302的输出端与至少一个超级电容301相连，为至少一个超级电容301充能；充电电源303的输入端与至少一个超级电容301相连，充电电源303的输出端与脉冲发生器100相连，为脉冲发生器100供电。
可选地，在一些实施例中，本申请实施例的脉冲调制器10，还包括：开关组件，开关组件设置于充电单元300和脉冲发生器100之间，以基于开关组件的开关状态控制脉冲发生器100充电或者放电。
应当理解的是，脉冲发生器100可以为MARX发生器，充电单元300利用至少一个超级电容301短时间内的大功率放电来为脉冲发生器100提供电能。在每次需要启用超高剂量率放疗技术之前，本申请实施例可以利用预充充电电源302给至少一个超级电容301充能，使其进入预备放电状态，从而在需要启用之时，利用至少一个超级电容301给后续充电电源模组(即充电电源303)供能。脉冲变压器200的前级装置通过脉冲变压器200对后续 功率源放电，进一步升高脉冲电压，同时隔离了脉冲调制器10与负载之间的直流电位，使得前级装置能够采用相对较低的工作电压，便于控制处理。
进一步地，为便于本领域技术人员进一步了解本申请实施例的脉冲调制器100，下面结合图3进行详细说明MARX发生器的工作原理。如图3和图4所示，图3和图4分别为MARX发生器储能和放电时的电路原理示意图，当开关断开时，电流方向为图3中箭头方向，14组储能电容(设置在储能器件内)并联充电；当开关导通时，电流方向为图4中箭头方向，14组储能电容串联放电，在输出端形成负高压，其幅度值为各储能电容的电压之和。由此，通过MARX发生器，将充电单元充在储能电容上的能量转化为脉冲高压能量，从而满足新型放射治疗技术的高剂量率、短放电时间的要求。
由此，本申请实施例利用至少一个超级电容以及辅助充电电源和开关组件替代传统脉冲调制器中的高压直流电源单元，在启用医用电子直线加速器系统之前完成超级电容模组的预充电，在启动之时利用超级电容的短时间放电即可实现一次超高剂量率的放射治疗技术。
需要说明的是，上述将脉冲调制器针对于放疗仅为示例性的，不作为本申请的限制，本领域技术人员可以根据实际情况在实际加速器领域中所有需要短时间内大功率工作的都可以运用，例如，电子器件的抗辐射研究、快速无损检测的实现以及研制基于加速器的闪光光源等。
