Description

一种供电设备、受电设备、芯片以及供电***
本申请要求于2022年11月16日提交国家知识产权局、申请号为202211436779.2、申请名称为“一种供电设备、受电设备、芯片以及供电***”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请的实施例涉及电源技术领域，尤其涉及一种供电设备、受电设备、芯片以及供电***。
背景技术
为了减少终端设备整机厚度以及电源散热对终端设备整机的影响，业界通常将体积较大的大功率电源与终端设备整机分体单独设计。尤其在终端设备上，超薄是高端终端设备的一个重要卖点，但终端设备厚度进一步降低往往受限于整机中的电源部分，究其原因主要是大功率电源器件及散热器体积较大，还有安规对空间布局的安全距离要求，成为整机厚度的瓶颈，因此电源与终端设备整机分体设计尤为重要。
然而，分体方案会带来接口和线缆通用性问题，如果采用定制接口和定制线缆，则需要为不同供电需求的终端设备单独设计定制化的接口、线缆以及电源，这将造成成本较高；定制化的方案中，由于不同供电需求的终端设备无法兼容同一电源，因此无法对电源进行归一化设计；如果不同供电需求的终端设备采用通用化的接口、线缆以及电源，则由于不同的终端设备具有不同的供电需求，提供供电电压的电源匹配时通用性差，即同一电源通常不能适配不同供电需求的终端设备，这样将同一电源与不同的终端设备通过通用接口和通用线缆互连时，可能会导致终端设备由于供电电压不够而无法正常工作，或者供电电压超过终端设备的额定电压而导致终端设备损坏；总之，通用化的方案中，不同的终端设备与电源通过通用化的接口和线缆互连时，互相组合不防呆。
发明内容
本发明的实施例提供一种供电设备、受电设备、芯片以及供电***，能够实现同一供电设备支持不同供电需求的受电设备。
为达到上述目的，本发明的实施例采用如下技术方案：
第一方面，提供一种供电设备，用于通过线缆连接受电设备。其中在结构上，该供电设备包括：电源模组、以及连接电源模组的第一控制接口以及第一供电接口；受电设备包括：***模组、受电模组、第二控制接口以及第二供电接口，***模组连接第二控制接口以及受电模组，受电模组连接第二供电接口。这样，供电设备通过线缆连接受电设备时，第一控制接口通过线缆中的线路连接所述第二控制接口，第一供电接口通过线缆中的线路连接第二供电接口。
基于上述的结构，在供电设备中，第一控制接口，被配置为获取受电设备通过第二控制接口发送的第一控制信息，第一控制信息由***模组获取的受电模组的供电需求生成；电源模组，被配置为根据第一控制信息指示的受电模组的供电需求，向第一供电接口输出第一直流电，第一直流电的电学参数被电源模组根据受电模组的供电需求调整为第一值。
这样在上述的示例中，由于受电设备可以通过***模组获取受电模组的供电需求，并生成第一控制信息发送至供电设备，供电设备在接收到第一控制信息后，可以根据第一控制信息指示的受电模组的供电需求控制电源模组输出至受电模组的直流电的电学参数，从而实现对受电设备供电的灵活调整，尤其对于具有不同供电需求的受电设备，由于本申请的实施例提供的方案能够实现对受电设备供电的灵活调整，因此也确保了供电设备能够支持具有不同供电需求的受电设备。
在一种可能的实现方式中，供电设备，还包括：连接电源模组的第三供电接口；受电设备，还包括连接***模组的第四供电接口；供电设备通过线缆连接受电设备时，第三供电接口通过线缆中的线路连接第四供电接口；电源模组，被配置为向第三供电接口输出第二直流电。这样，由于需要通过***模组获取受电模组的供电需求，因此需要首先通过供电设备对该***模组上电，该实现方式中可以确保***模组在第二直流电供电时能够正常工作。当然，对***模组上电方式还有其他方式，在下述的第二方面具体进行描述。
在一种可能的实现方式中，当***模组上电后，还可以进一步根据***模组的供电需求进一步调整第二直流电Vsys的电学参数。例如，***模组，被配置为根据***模组的供电需求生成第二控制信息； 其中，***模组的供电需求可以包括由***模组的负载状态(轻载或重载)、工作状态(例如息屏、或亮屏、开机或待机等)等确定的电学参数，例如可以是电压、电流以及功率。第一控制接口，还被配置为获取受电设备通过第二控制接口发送的第二控制信息，第二控制信息由***模组获取的***模组的供电需求生成；电源模组，被配置为根据第二控制信息指示的***模组的供电需求，将第二直流电的电学参数调整至第二值。
在一种可能的实现方式中，供电设备还包括检测电路，检测电路连接于电源模组和第一控制接口之间；受电设备还包括反馈电路，反馈电路连接于***模组和第二控制接口之间；第一控制接口，具体被配置为接收反馈电路通过第二控制接口发送的第一控制信息，第一控制信息由反馈电路根据***模组获取的受电模组的供电需求生成；检测电路，被配置为检测第一控制信息生成受电模组的供电需求。在该示例中，上述的受电模组的供电需求可以由反馈电路转换为固定格式的第一控制信息通过线路传输至检测电路，并由检测电路在该固定格式的第一控制信息中检测出相应的受电模组的供电需求然后传输至电源模组，以对电源模组实现上述示例中相应的控制。例如第一控制信息可以是协议信号、或者数字信号(例如脉宽调制(pulse width modulation，PWM)信号)、模拟信号以及通用输入输出(general-purpose input/output，GPIO)信号等形式的信号中的一种或多种。
在一种可能的实现方式中，供电设备还包括检测电路，检测电路连接于电源模组和第一控制接口之间；受电设备还包括反馈电路，反馈电路连接于***模组和第二控制接口之间；第一控制接口，还被配置为接收反馈电路通过第二控制接口发送的第二控制信息，第二控制信息由反馈电路根据***模组获取的***模组的供电需求生成；检测电路，被配置为检测第二控制信息生成***模组的供电需求。在该示例中，上述的***模组的供电需求可以由反馈电路转换为固定格式的第二控制信息通过线路传输至检测电路，并由检测电路在该固定格式的第二控制信息中检测出相应的***模组的供电需求然后传输至电源模组，以对电源模组实现上述示例中相应的控制。例如第二控制信息可以是协议信号、或者数字信号(例如PWM信号)、模拟信号以及GPIO信号等形式的信号中的一种或多种。
在一种可能的实现方式中，供电设备，还被配置为接收受电设备发送的反馈信息，反馈信息为受电设备接收到第一直流电后通过检测第一直流电的电学参数的检测值生成；反馈信息携带第一直流电的电学参数的检测值；电源模组，被配置为根据检测值，将第一直流电的电学参数调整至第一值。在该示例中，可以通过反馈信息实现闭环的FB调节使得第一直流电的电学参数始终稳定在与受电模组的供电需求匹配的电学参数上，避免了第一直流电的电学参数不稳定造成的供电功率不足或功率浪费。
在一种可能的实现方式中，供电设备还包括检测电路，检测电路连接于电源模组和第一控制接口之间；受电设备还包括反馈电路，反馈电路连接于受电模组和第二控制接口之间；第一控制接口，被配置为接收反馈电路通过第二控制接口发送的反馈信息；检测电路，被配置为检测反馈信息获取检测值。电源模组，被配置为根据检测值，将第一直流电的电学参数调整至第一值。在该示例中，首先，通过检测值实现闭环的FB调节使得第一直流电的电学参数始终稳定在与受电模组的供电需求匹配的电学参数上，避免了第一直流电电学参数不稳定造成的供电功率不足或功率浪费。其次，上述的检测值可以由反馈电路转换为固定格式的反馈信息通过线路传输至检测电路，并由检测电路在该固定格式的反馈信息中检测出相应的检测值然后传输至电源模组，以对电源模组实现上述示例中相应的控制。例如反馈信息可以是协议信号、或者数字信号(例如PWM信号)、模拟信号以及GPIO信号等形式的信号中的一种或多种。这样所有的控制信息(第一控制信息、第二控制信息以及反馈信息)均通过反馈电路在一条线路传输至检测电路，因此在线缆设计时仅通过一条线路即可传输第一控制信息、第二控制信息以及反馈信息，因此仅通过线缆中的一个引脚即可实现对应连接器中的接口的插接，这样的设置更有利于支持线缆的正反插拔设计。

具体实施方式
下面将结合附图，对本申请一些实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请所提供的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
以下，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或 者更多个该特征。在本申请实施例的描述中，除非另有说明，“多个”的含义是两个或两个以上。
下面将结合附图，对本申请的实施例中的技术方案进行描述。
图1是本申请实施例提供的一种终端设备100的结构示意图。终端设备100可以是广告屏(广告牌)、显示器、电视(如智慧屏)、笔记本电脑、平板电脑、车载设备等大屏终端设备。可选的，在一些场景下，终端设备100可以是手机、电子阅读器或可穿戴设备等设备。图1所示实施例以终端设备100是显示设备为例进行说明。
终端设备100可以包括壳体110和屏组件120。
壳体110可以包括边框和后盖。边框可以环绕设于后盖的周缘。壳体110例如可以包括终端设备100的中框。在一个示例中，终端设备100的中框可以收容于边框的内周。在另一个示例中，终端设备100的中框可以充当壳体110的边框。屏组件120可以是为终端设备100提供显示功能的组件。用户可以观看屏组件120以欣赏图像、视频等媒体资源。屏组件120可以安装于壳体110上。屏组件120的周缘可以抵靠在边框的内沿。边框可以将屏组件120固定在壳体110上。屏组件120和后盖可以分别安装于边框的两侧，使得壳体110可以为终端设备内部的器件，尤其是屏组件120上的器件，提供机械保护的功能。屏组件120例如可以固定于终端设备100的中框上。在一些示例中，以液晶显示为例，屏组件120可以包括背光模组以及设置于背光模组出光侧的液晶面板。为了控制背光模组中的灯板以及液晶面板进行图像显示，终端设备100可以包括处理器、存储器、控制器、连接器、驱动板、集成电路、芯片、电源等控制模组。
为了减少终端设备100的整机厚度以及电源散热对终端设备整机的影响，业界通常将体积较大的大功率电源与终端设备整机分体单独设计。
结合图2所示，提供了一种将电源与终端设备整机分立设计的供电***。参照图2所示，供电***包括作为受电设备100的终端设备以及作为电源的供电设备200。受电设备100和供电设备200通过线缆300连接。在一些示例中供电设备200也称作电源坞(DOCK)、电源盒子、适配器等。其中，受电设备100和供电设备200上均设置有用于插接线缆300的连接器，通常连接器上设置有接口(或引脚)，这些接口或引脚一来用于连接受电设备100和供电设备200内的模组，例如受电设备100上的连接器内部的接口用来连接受电设备100内部的***模组101、受电模组(例如灯板102)等等；供电设备200上的连接器内部的接口用来连接电源模组201等等；另外，这些接口或引脚还提供与线缆300插接，从而将受电设备100上的连接器内部的接口通过线缆300内部的线路与供电设备200上的连接器内部的接口连通，从而实现供电设备200内部的模块与受电设备100内部的模块的连通。
如图2所示，供电设备200中包括电源模组201，电源模组201包括AC/DC变换电路，用于将220V的交流市电转换为用于为受电设备100供电的一个或多个直流电。例如，当需要为受电设备100中的***模组101以及灯板102供电时，则AC/DC变换电路201可以将市电转换为分别为***模组101供电的Vsys以及为灯板102供电的VLED。AC/DC变换电路包括但不限于一路或多路基于LLC变换器或反激变换器的电压变换电路。通常，***模组101是受电设备100的控制中心，例如可以包括处理器、存储器、总线以及接口等，在一些示例中，***模组可以是片上***(system on chip，SOC)、中央处理器(central processing unit，CPU)、微控制单元(microcontroller unit，MCU)、现场可编程门阵列(field-programmable gate array，FPGA)等具有逻辑处理功能的集成电路；灯板102为受电设备100的受电模组，当然，在本申请的实施例中受电模组主要是以灯板102为例进行说明，通常在受电设备100中还具有其他类型的受电模组，例如射频、功放等其他用电电路。
如上所述，虽然电源与终端设备整机分体设计有利于终端整体的超薄化，但是分体方案会带来接口和线缆通用性问题，如果采用定制接口和定制线缆，则需要为不同供电需求的终端设备单独设计定制化的接口、线缆以及电源，这将造成成本较高，在定制化的方案中，由于不同供电需求的终端设备无法兼容同一电源，因此无法对电源进行归一化设计，例如，65寸的显示设备与55寸的显示设备的灯板具有明显不同的供电需求，因此对于接口、线缆以及电源的额定电压设计需要做定制化设计。如果不同供电需求的终端设备采用通用化的接口、线缆以及电源，则由于不同的终端设备具有不同的供电需求，提供供电电压的电源匹配时通用性差，即同一电源通常不能适配不同供电需求的终端设备，这样将同一电源与不同的终端设备通过通用接口和通用线缆互连时，可能会导致终端设备由于供电电压不够而无法正常工作，或者供电电压超过终端设备的额定电压而导致终端设备损坏，总之通用化的方案中，不同的终端设备与电源通过通用化的接口和线缆互连时，互相组合不防呆(fool-proofing)。
为解决上述问题，参照图3所示，本申请的实施例提供一种供电***，包括供电设备200以及受电设备100。供电设备200通过线缆300与受电设备100连接，供电设备200用于向受电设备100供电。
供电设备200包括：电源模组201、以及连接电源模组201的第一控制接口202以及第一供电接口203。受电设备100包括：***模组101、灯板102、第二控制接口103以及第二供电接口104，***模组101连接第二控制接口103以及灯板102，灯板102连接第二供电接口104。
供电设备200通过线缆300连接受电设备100时，第一控制接口202通过线缆中的线路连接第二控制接口103，这样在***模组101与电源模组201之间形成控制信息的传输路径；第一供电接口203通过线缆300中的线路连接第二供电接口104，这样在灯板102与电源模组201之间形成供电信号的传输路径。
基于上述图3示出的硬件结构，对各个受电设备100以及供电设备200中各个模块的具体功能说明如下：
***模组101，被配置为获取灯板102的供电需求；第二控制接口103，被配置为向第一接口发送第一控制信息，其中第一控制信息是由***模组101获取的灯板102的供电需求生成；由于第一控制接口202与第二控制接口103通过线缆300中的线路3连接，因此该第一控制信息可以直接传输至第一控制接口202。
第一控制接口202，被配置为获取受电设备100通过第二控制接口103发送的第一控制信息，第一控制信息为受电设备100根据对灯板102的供电需求的检测结果生成；其中，在一些方案中第一控制信息可以是灯板102的供电需求本身，灯板102的供电需求可以包括由设备规格、厂家信息、背光供电方案(例如不同背光功耗场景下的灯板供电参数，不同背光亮度场景下的灯板供电参数等)等确定的电学参数，例如可以是电压、电流以及功率。
电源模组201，被配置为根据第一控制信息指示的灯板102的供电需求，向第一供电接口输出第一直流电，例如将接收的交流电转换为第一直流电Vled并输出至第一供电接口203，第一直流电Vled的电学参数被电源模组201根据第一控制信息指示的灯板102的供电需求调整为第一值。由于第一供电接口203通过线缆300中的线路1连接第二供电接口104，因此，第一直流电Vled可以被直接传输至第二供电接口104。例如该第一值可以是灯板102的供电需求对应的电压、电流以及功率。在图3中，电源模组201可以包括AC/DC变换电路以及DC/DC变换电路，其中，AC/DC变换电路的输入端用于输入交流电，例如可以是220V的交流电，AC/DC变换电路可以将交流电转换为第一直流电Vled；此外，DC/DC变换电路可以根据第一控制信息指示的灯板的供电需求调整第一直流电Vled的电学参数。
灯板102，被配置为通过第二供电接口104接收第一供电接口203输出的第一直流电Vled。这样，通过第一直流电Vled为灯板102供电。
这样在上述的示例中，由于受电设备可以通过***模组检测灯板的供电需求，并生成用于指示灯板的供电需求的第一控制信息，供电设备可以根据第一控制信息控制输出至受电模组的直流电的电学参数，由于第一控制信息可以反映灯板的供电需求，即第一控制信息指示的灯板的供电需求与输出至受电模组的直流电的电学参数相关联，从而可以实现对受电设备供电的灵活调整，尤其对于具有不同供电需求的受电设备，由于本申请的实施例提供的方案能够实现对受电设备供电的灵活调整，因此也确保了供电设备能够支持具有不同供电需求的受电设备。
在一些可能的实现方式中，参照图3所示，供电设备200，还可以进一步包括：连接电源模组201的第三供电接口204；受电设备100，还包括连接***模组101的第四供电接口105；供电设备200通过线缆300连接受电设备100时，第三供电接口204通过线缆300中的线路2连接第四供电接口105。
电源模组201，被配置为将接收的交流电转换为第二直流电Vsys，并输出至第三供电接口204。***模组101，被配置为通过第四供电接口105接收电源模组201通过第三供电接口204输出的第二直流电Vsys，第二直流电Vsys由电源模组201对接收的交流电转换生成。通常，电源模组201中并不限定AC/DC变换电路以及DC/DC变换电路的数量，例如在本申请的示例中，电源模组201可以具有另一组AC/DC变换电路以及DC/DC变换电路，其中该另一组AC/DC变换电路以及DC/DC变换电路可以将交流电转换为第二直流电Vsys，并通过该第二直流电Vsys直接为***模组101供电。这里， Vsys的电学参数应该是满足***模组101的最低工作需求的。
这样，可以先由供电设备对该***模组101上电，以通过***模组101检测并获取灯板102的供电需求，从而确保***模组在第二直流电Vsys供电时能够正常工作。当然在一些示例中，为了降低成本电源模组201中也可以设置一组AC/DC变换电路，两组DC/DC变换电路，通过两组DC/DC变换电路共用同一组AC/DC变换电路的输出分别为灯板和***模组供电。
此外，在一些示例中，当***模组101上电后，还可以进一步根据***模组101的供电需求调整第二直流电Vsys的电学参数。例如，***模组101，被配置为根据***模组101的供电需求生成第二控制信息；其中，***模组101的供电需求可以包括由***模组的负载状态(轻载或重载)、工作状态(例如息屏、或亮屏、开机或待机等)等确定的电学参数，例如可以是电压、电流以及功率。***模组101，还被配置为将第二控制信息发送至第二控制接口103。第一控制接口202，还被配置为获取***模组101通过第二控制接口103发送的第二控制信息；电源模组201，被配置为根据第一控制接口202获取的第二控制信息，将第二直流电Vsys的电学参数调整至第二值并输出至第三供电接口204。例如该第二值可以是***模组101的供电需求对应的电压、电流以及功率。***模组101，被配置为通过第四供电接口105接收电源模组201通过第三供电接口204输出的第二直流电Vsys。这样，由于第二控制信息可以反映***模组的供电需求，即第二控制信息指示的灯板的供电需求与输出至***模组的直流电的电学参数相关联，从而可以实现对***模组供电的灵活调整。
参照图4所示，在一些示例中，为了首先对***模组101上电，受电设备100可以设置有与***模组101连接的电池108，通过该电池108直接对***模组101提供第二直流电Vsys，当然在一些示例中，参照图5所示，也可以通过连接在第二供电接口104与***模组101之间的变换电路109(例如可以是DC/DC)将第一直流电的电学参数进行转换生成第二直流电Vsys。
为了在第一控制信息的控制下确保电源模组201能够按照灯板102的供电需求输出稳定的第一直流电Vled，本申请的实施例中还可以引入闭环反馈(feed back，FB)调节机制。即，参照图6所示，供电设备200，还包括连接电源模组201的第一反馈接口205；受电设备100，还包括与灯板102连接的第二反馈接口106；供电设备200通过线缆300连接受电设备100时，第一反馈接口205通过线缆300中的线路4连接第二反馈接口106；第一反馈接口205，被配置为接收灯板102通过第二反馈接口106发送的反馈信息，该反馈信息可以携带第一直流电Vled的电学参数的检测值，检测值由灯板102对第二供电接口105接收的第一直流电Vled的电学参数检测生成；电源模组201，被配置为根据检测值将第一直流电Vled的电学参数调整至第一值。这样通过闭环的FB调节使得第一直流电Vled电学参数始终稳定在与灯板102的供电需求匹配的电学参数上，避免了第一直流电Vled电学参数不稳定造成的供电功率不足或功率浪费。
在一些示例中，本申请的实施例并不限定第一控制信息、第二控制信息以及反馈信息的具体形式。例如，第一控制信息、第二控制信息可以是由***模组101直接对灯板102以及自身的供电需求检测后生成的协议信号、或者数字信号(例如脉宽调制(pulse width modulation，PWM)信号)、模拟信号以及通用输入输出(general-purpose input/output，GPIO)信号等形式的信号中的一种或多种，并通过图6中的线路3传输至电源模组201。反馈信息可以是灯板102直接检测的第一直流电Vled电学参数值，并通过线路4反馈至电源模组201。当然，由于需要通过线缆中的线路3以及线路4分别传输上述的两类信号，因此在连接器以及线缆的设计上，对于支持正反插接的设计难度较大。因此，参照图6和图7所示本申请的实施例提供的供电设备200还包括检测电路206，以及受电设备100还可以包括反馈电路107。这样，上述的灯板的供电需求、***模组的供电需求以及检测值均可以由反馈电路107分别转换为固定格式的第一控制信息、第二控制信息以及反馈信息，然后通过线路3传输至检测电路206，并由检测电路206在该固定格式的第一控制信息、第二控制信息以及反馈信息中检测出相应的灯板的供电需求、***模组的供电需求以及检测值然后传输至电源模组201，以对电源模组201实现上述示例中相应的控制。
具体的，参照图8所示，对于第一控制信息的传输过程：供电设备200还包括检测电路206，检测电路206连接于电源模组201和第一控制接口202之间；受电设备100还包括反馈电路107，反馈电路107连接于***模组101和第二控制接口103之间。反馈电路107，被配置为根据***模组101获取的灯板102的供电需求生成第一控制信息。反馈电路107，还被配置为将第一控制信息发送至第二控制接口103。第一控制接口202，还被配置为接收反馈电路107通过第二控制接口103发送的第一 控制信息；检测电路206，被配置为检测第一控制信息生成灯板102的供电需求。
对于第二控制信息的传输过程：反馈电路107，被配置为根据***模组101获取的***模组101的供电需求生成第二控制信息。反馈电路107，还被配置为将第二控制信息发送至第二控制接口103。第一控制接口202，还被配置为接收反馈电路107通过第二控制接口103发送的第二控制信息；检测电路206，被配置为检测第二控制信息生成***模组101的供电需求。
对于反馈信息的传输过程：灯板102，被配置为检测第二供电接口105接收的第一直流电的电学参数，生成第一直流电的电学参数的检测值；灯板102，还被配置为将第一直流电的电学参数的检测值发送至反馈电路107；反馈电路107，被配置为向第二控制接口103发送反馈信息，反馈信息携带检测值。供电设备200还包括检测电路206，检测电路206连接于电源模组201和第一控制接口202之间；第一控制接口202，被配置为接收反馈电路107通过所述第二控制接口103发送的反馈信息，所述反馈信息携带所述第一直流电的电学参数的检测值；检测电路206，被配置为检测反馈信息获取检测值；电源模组201，被配置为根据检测值，将第一直流电的电学参数调整至第一值。
可选地，在该示例中由于将携带检测值的反馈信息复用至通过第一控制接口202和第二控制接口103传输，因此可以将检测值通过反馈电路107传输至检测电路206，这样在供电设备200和受电设备100之间可以减少一条线路4，也即各控制信息均通过一条线路传输，因此在线缆设计时仅通过一条线路即可传输第一控制信息、第二控制信息以及反馈信息，从而仅通过线缆中的一个引脚即可实现对应连接器中的接口的插接，这样的设置更有利于支持线缆的正反插拔设计。
当然，为了实现上述各个反馈信息的生成和检测，检测电路206以及反馈电路107需要采用具有相应信号转换功能的电路，例如：检测电路以及反馈电路可以采用包括协议IC、数字电路、模拟电路、GPIO电路中的一种或多种。
在下述方案中对电源模组的具体结构说明如下：
为了对灯板供电，参照图9所示，电源模组201可以包括第一变换电路2011和第二变换电路2012，其中第一变换电路2011可以为AC/DC变换电路，第二变换电路2012可以为DC/DC变换电路。第一变换电路2011连接第二变换电路2012，第二变换电路2012连接第一控制接口202以及第一供电接口203；第一变换电路2011，被配置为将接收的交流电转换为第一直流电；第二变换电路2012，被配置为根据在第一控制接口202获取的第一控制信息指示的灯板的供电需求，将第一直流电的电学参数调整至第一值并输出至第一供电接口203。
此外，为了对***模组供电，参照图9所示，电源模组201，包括第三变换电路2013，第三变换电路2013连接第三供电接口204；第三变换电路2013，被配置为将接收的交流电转换为第二直流电，并输出至第三供电接口204。第三变换电路2013可以为AC/DC变换电路。
当然，为了实现对输出至***模组的第二直流电的电学参数进行调整，参照图10所示，电源模组201，还可以包括第四变换电路2014，第四变换电路2014连接于第三变换电路2013和第三供电接口204之间，第四变换电路2014还连接第一控制接口202；第四变换电路2014可以为DC/DC变换电路。第一控制接口202，还被配置为获取受电设备通过第二控制接口发送的第二控制信息；第四变换电路2014，被配置为根据第二控制信息指示的***模组的供电需求，将第二直流电的电学参数调整至第二值并输出至第三供电接口204。
在上述图9和图10的示例中，灯板供电和***模组供电分别采用独立的AC/DC变换电路。为了节约成本，也可以将灯板供电和***模组共用同一组AC/DC变换电路。参照图11所示，电源模组201可以包括第一变换电路2011和第二变换电路2012，以及第四变换电路2014，其中，第一变换电路2011和第二变换电路2012的连接关系以及功能描述可以参照图7所示，区别在于，图11中的电源模组201还包括第四变换电路2014，第四变换电路2014连接于第一变换电路2011和第三供电接口204之间；第一控制接口202，还被配置为获取***模组通过第二控制接口发送的第二控制信息，第四变换电路2014，被配置为根据第二控制信息指示的***模组的供电需求，控制第一直流电的电学参数调整至第二值并输出至第三供电接口204。
当然上述图9-图11提供的电源模组的示例仅仅是一些可选示例，在此基础上本领域人员还可以对电源模组进一步调整扩展出更多的结构。例如：参照图12所示，第一变换电路2011具体可以为整流电路，则在该整流电路的输入端和输出端还可以进一步设置电磁兼容性(electromagnetic compatibility，EMI)滤波防护电路，在该整流电路的输出端还可以设置用于功率因数调整的功率因数校正(power  factor correction，PFC)电路。另外，在图10示出的示例中，根据Vsys的实际供电需求，第四变换电路2014具体可以采用低功率效率更高的反激变换电路或高功率效率更高的谐振(LLC)变换电路。由于第二变换电路2012主要用于对灯板供电；并且为了配合背光的动态范围，因此灯板的功率范围较宽(可能存在较大的功率以及较小的功率)，因此第二变换电路2012可以采用在高功率范围内具有更高效率的LLC变换电路。此外，如图12所示，Vsys和Vled也可以共用第二变换电路2012，这样可以在第二变换电路2012后设置多组DC/DC变换电路分别为***模组和灯板供电。具体地，可以在第二变换电路2012之后，采用第一控制信息控制一组DC/DC变换电路调整第二变换电路2012输出的第一直流电的电学参数生成Vled；采用第二控制信息控制另一组DC/DC变换电路调整第二变换电路2012输出的第一直流电的电学参数生成Vsys。此外，为了实现供电设备的正常工作Vsys还可用于向供电设备供电，例如可以向电源模组中的控制电路供电。
参照图13所示，为了实现对供电设备以及受电设备的过流保护、过压保护、欠压保护等保护功能，本申请的实施例提供的方案还可以对线路1上的第一直流电Vled以及线路2上的第二直流电Vsys进行电源规格检测。其中，参照图13所示，检测电路206还连接第一供电接口203以及第三供电接口204，被配置为检测第一供电接口203的第一直流电的电学参数，以及检测第三供电接口204的第二直流电的电学参数。当然在确定电源规格不符合要求时可以触发相应的保护机制，例如控制电源模组断电。另外，参照图13所示供电设备，还可以进一步包括连接于电源模组201和第一供电接口203之间的开关K1；开关K1的控制端连接于检测电路206；检测电路206，被配置为根据第一直流电的电学参数控制开关的导通状态，这样可以单独实现对灯板供电的通断。
另外，当本申请的实施例中，也可以通过Vsys对供电设备200的检测电路206以及受电设备100的反馈电路107供电。此外，反馈电路107也可以对Vsys进行供电规格检测并将检测结果反馈至检测电路206，由检测电路206对Vsys进行闭环的动态调整。另外需要说明的是，灯板102输出的对第二直流电的电学参数的检测值也可以经由线路4传输至检测电路206，由检测电路206根据该检测值控制电源模组201对第二直流电Vsys的电学参数进行闭环的动态调整。
在本申请的实施例中并不限定线缆300的形式，其中线缆300中也可以设置有线缆IC，例如线缆可以是电子标签线缆(electronically marked cable，E-Marker)，线缆IC可以存储有线缆电子标签，这样在本申请的实施例中受电设备可以在线缆电子标签对应的能力范围内动态调整输出的直流电，避免线缆损坏。
在图14中，还是示出了反馈电路107以及检测电路206的具体形式可以采用协议IC；在图15中还示出了还是示出了反馈电路107以及检测电路206的具体形式可以采用模拟和\或数字电路；在图16中还示出了还是示出了反馈电路以及检测电路的具体形式可以采用GPIO。其中在图13-图16中，电源模组201可以采用上述图9-图13中示出的任一结构形式的电源模组。

其中在步骤S106之后，为了实现第一直流电在相应的供电需求下稳定的输出，受电设备还可以用于检测接收的第一直流电Vled的电学参数，生成第一直流电Vled的电学参数的检测值；将第一直流电的电学参数的检测值携带在反馈信息中发送至供电设备。之后，供电设备接收受电模组发送的检测值；根据检测值控制电源模组将第一直流电的电学参数调整至第一值，从而实现对第一直流电Vled的电学参数的闭环反馈调节。进一步的，受电设备还可以将检测到的检测值生成上述的协议信号、数字信号、模拟信号或GPIO信号等形式的反馈信息发送至供电设备。供电设备接收受电设备发送的反馈信息后，检测反馈信息获取检测值；最后，根据检测值控制电源模组将第一直流电的电学参数调整至第一值。
另外，参照图18所示，本申请的实施例提供的方案还可以对第二直流电Vsys进行动态调整，具体包括如下步骤：
S101、供电设备控制电源模组将交流电转换为第二直流电Vsys并输出至受电设备的***模组。
S201、受电设备并对***模组进行供电需求检测。
当然，***模组的供电需求在受电设备不同的工作状况下是动态变化的，例如当整机发生业务切换时，***模组的供电需求相应的发生变化。
如上所述，***模组的供电需求可以包括由***模组的负载状态(轻载或重载)、工作状态(例如息屏、或亮屏、开机或待机等)等确定的电学参数，例如可以是电压、电流以及功率。
S202、受电设备根据***模组的供电需求生成第二控制信息。

具体的，在步骤S203中，如上所述当供电设备包括检测电路，以及受电设备包括反馈电路时，受电设备还可以将***模组的供电需求生成上述的协议信号、数字信号、模拟信号或GPIO信号。例如：S203具体可以是受电设备根据对***模组的供电需求生成第二控制信息，将第二控制信息发送至供电设备。
S204、供电设备接收受电设备发送的第二控制信息。
当供电设备接收到的信号为上述的协议信号、数字信号、模拟信号或GPIO信号形式的第二控制信息时，供电设备具体用于检测第二控制信息生成***模组的供电需求。
