具体实施方式
体现本公开特征与优点的一些典型实施例将在后段的说明中详细叙述。应理解的是本公开能够在不同的实施方式上具有各种的变化，其皆不脱离本公开的范围，且其中的说明及图示在本质上当作说明之用，而非架构于限制本公开。
请参阅图1、图2、图3及图4，其中图1为本公开第一优选实施例的电源装置的组合结构示意图，图2为图1所示的电源装置的爆炸结构示意图，图3为图1所示的平面变压器的第二绕组的结构示意图，图4为图1所示的平面变压器的第二印刷电路板的内部布线示意图。本实施例的电源装置1A可接收输入电能，并转换为输出电能，以提供给负载(未图示)使用。电源装置1A包含至少一电源电路组件7及平面变压器1。电源电路组件7包含第一印刷电路板70及电源转换模块71。第一印刷电路板70包含相对设置的第一表面700及第二表面701，电源转换模块71设置于第一表面700上。
于一些实施例中，电源转换模块71用以转换输入电能为过渡电能，且可包含至少一种电子元件，可为但不限于开关元件、控制器、二极管、电阻及积层陶瓷电容等。于一些实施例中，如图1所示，电源转换模块71的所有电子元件可分别独立设置于第一表面700上。于其他实施例中，电源转换模块71的所有电子元件亦可先封装为一个整体的模块后再设置于第一表面700上。
于其他实施例中，电源电路组件7还可包含功率因数校正模块(未图示)、电磁干扰(EMI)/无线射频干扰(RFI)模块及输入电容，功率因数校正模块(未图示)、电磁干扰(EMI)/无线射频干扰(RFI)模块及输入电容分别设置于第一表面700上，其中功率因数校正模块用以对输入电能进行功率因数校正，电磁干扰(EMI)/无线射频干扰(RFI)模块用以抑制电磁干扰及无线射频干扰，输入电容则用以稳压。
本实施例的平面变压器1可满足电路超薄化高频需求，且适合全自动化组合和测试，平面变压器1包含磁芯组件2、至少一第二印刷电路板3及至少一绕组模块4。
磁芯组件2包含第一磁芯20及第二磁芯21，第一磁芯20及第二磁芯21位于平面变压器1的相对两侧。此外，第一磁芯20及第二磁芯21的至少其中之一与第一印刷电路70板相邻设，例如图2所示，第二磁芯21与第一印刷电路板70相邻设，且第一印刷电路板70(或电源电路组件7)位于电源装置1A的最外侧。
第二印刷电路板3的个数可为一个或复数个，图2则例示了一个第二印刷电路板3，第二印刷电路板3设置于第一磁芯20及第二磁芯21之间，且每一第二印刷电路板3包含第一绕组30(如图4所示)，第一绕组30形成于第二印刷电路板3内，且可由第二印刷电路板3内的迹线或导体所构成。
绕组模块4的个数可为一个或复数个，图2则例示了一个绕组模块4，绕组模块4设置于第一磁芯20及第二磁芯21之间，且可位于第二印刷电路板3及第一磁芯20之间， 此外，绕组模块4还包含第二绕组40及注塑层41。第二绕组40可为但不限于由导电片，例如铜片，以冲压方式所形成。注塑层41可利用塑料注塑方式而形成于第二绕组40上，并包覆第二绕组40的外表面的至少部分，注塑层41可使平面变压器1达到安规防护要求。另外，在本实施例中，第二印刷电路板3及绕组模块4两者更分别为独立元件，即第二印刷电路板3及绕组模块4并非一体成形。
由上可知，本公开的电源装置1A包含了电源电路组件7及平面变压器1，且电源电路组件7及平面变压器1两者之间可以像乐高积木般堆叠的方式进行组合，如此一来，由于电源电路组件7及平面变压器1两者可进行组合或拆卸，故电源装置1A在生产时便无须备齐所有电子元件才能上线制作组装，即电源电路组件7及平面变压器1可分别在不同地进行组装后再汇集而构成电源装置1A，因此电源装置1A在制作上更为方便。此外，由于电源电路组件7及平面变压器1两者之间可以像乐高积木般堆叠的方式进行组合，故在维修上，电源电路组件7及平面变压器1可个别进行维修，因此无须对电源装置1A完全拆除，如此一来，可提升电源装置1A内的元件利用率。更甚者，由于平面变压器1包含分别为独立元件的第二印刷电路板3及绕组模块4，其中第二印刷电路板3包含第一绕组30，绕组模块4包含第二绕组40，因此平面变压器1实将变压器所需的绕组采分离设计而形成第一绕组30及第二绕组40，并分别位于两个独立元件上，如此一来，平面变压器1可因第二绕组40位于绕组模块4上而减少第二印刷电路板3的层数，使第二印刷电路板3的层数相较于传统平面变压器的单一电路板的层数少，进而使平面变压器1的生产周期较短，且使第二印刷电路板3的制程工艺较低而容错率高，进而减少平面变压器1的生产成本，更甚者，本公开的平面变压器1的可调性优选。
于一些实施例中，第一绕组30构成平面变压器1的初级侧绕组及次级侧绕组两者的其中之一，第二绕组40构成平面变压器1的初级侧绕组及次级侧绕组两者的其中另一。另外，第二绕组40的厚度可大于或等于0.01mm，且小于或等于1.5mm，且第二绕组40的匝数为两圈以上。再者，第一绕组30及第二绕组40之间的安规防护间距为0.4mm，而此安规防护间距可由注塑层41的厚度来实现，或由第二印刷电路板3的厚度来实现。又注塑层41的厚度可大于或等于0.4mm，并小于或等于0.8mm。
于一些实施例中，磁芯组件2还包含第一边柱22、第二边柱23及中柱24。第一边柱22及第二边柱23位于磁芯组件2的相对两侧，中柱24位于第一边柱22及第二边柱23之间，且第一边柱22、第二边柱23及中柱24位于第一磁芯20及第二磁芯21之间。另外，如图2所示，第一边柱22、第二边柱23及中柱24可分别由两个子磁柱所构成，第一边柱22的其中之一子磁柱、第二边柱23的其中之一子磁柱及中柱24的其中之一子磁柱连接于第一磁芯20，第一边柱22的另一子磁柱、第二边柱23的另一子磁柱及中柱24的另一子磁柱连接于第二磁芯21。当然，于其它实施例中，第一边柱22、第二边柱23及中柱24可分别为单一结构所构成而连接于第一磁芯20或连接于第二磁芯21。
于一些实施例中，第二印刷电路板3包含第一中空孔洞31，绕组模块4包含第二中 空孔洞42，其中第一中空孔洞31贯穿第二印刷电路板3，第二中空孔洞42贯穿绕组模块4，且第一中空孔洞31及第二中空孔洞42分别与磁芯组件2的中柱24相对应位置设置，当磁芯组件2的第一磁芯20及第二磁芯21由平面变压器1的相对两侧分别扣合于第二印刷电路板3及绕组模块4上时，中柱24会穿设第一中空孔洞31及第二中空孔洞42。
于一些实施例中，注塑层41包含第一脚座区44，位于注塑层41的第一侧，且包含第一上表面及第一下表面，第一上表面及第一下表面大致与第二印刷电路板3平行。平面变压器1还包含至少一导体5，例如第一导电引脚，导体5可于注塑层41以注塑方式形成于第二绕组40上时同步设置于注塑层41的第一脚座区44的位置，其中导体5大致与第一脚座区44的第一上表面及第一下表面垂直，且导体5是部分被注塑层41包覆，此外，导体5更暴露于第一脚座区44的第一上表面及第一下表面而朝垂直第一脚座区44的方向延伸，其中导体5暴露于第一脚座区44的部分可与第二印刷电路板3的迹线或导体以焊接方式导电连接，例如与第一绕组30以焊接方式导电连接，且导体5可插设于系统板(未图示)上。
另外，于其他实施例中，第一印刷电路板70还包含至少一第一穿设孔72，第一穿设孔72的个数与设置位置皆与导体5的个数与设置位置相对应，每一第一穿设孔72可供对应的导体5穿设，使得导体5与第一印刷电路板70组接，借此电源电路组件7及平面变压器1两者之间可以像乐高积木般堆叠的方式进行组合，且导体5可通过第一印刷电路板70的迹线(未图示)或导体(未图示)与电源转换模块71电连接。
于一些实施例中，第二印刷电路板3包含至少一第二穿设孔32，第二穿设孔32与对应的导体5相对位置设置，每一第二穿设孔32可供对应的导体5穿设，且使导体5的至少部分与第二印刷电路板3的迹线或导体电连接。
于其它实施例中，注塑层41包含第二脚座区45，位于注塑层41的第二侧，其中注塑层41的第一侧与第二侧为相对，且第二脚座区45包含第二上表面及第二下表面，第二脚座区45的第二上表面及第二下表面大致与第二印刷电路板3平行。此外，绕组模块4还包含至少一第二导电引脚46，例如图3所示两个第二导电引脚46，第二导电引脚46至少部分设置于第二脚座区45内，其中每一第二导电引脚46的一端与第二绕组40对应的端部连接，并设置于第二脚座区45内，每一第二导电引脚46的另一端则外露于第二脚座区45的第二上表面或第二下表面的上表面或下表面而朝垂直第二脚座区45的方向延伸，两个第二导电引脚46可插设于系统板上。于一些实施例中，两个第二导电引脚46可分别与第二绕组40的两个相对端部为一体成型结构，换言之，即两个第二导电引脚46可分别由第二绕组40的两个相对端部直接延伸所形成，且为了使第二导电引脚46的另一端暴露于第二脚座区45的第二上表面或第二下表面并朝垂直第二脚座区45的方向延伸，每一第二导电引脚46可由第二绕组40对应的端部以90度弯折至少一次。
于一些实施例中，由导电片构成的第二绕组40还包含表面400及凹陷部401，其中凹陷部401从表面400内凹形成，通过凹陷部401的设计，可减少肌肤效应，进而增加平 面变压器1的转换效率。于其它实施例中，当第二导电引脚46与第二绕组40的对应端部为一体成型结构时，第二导电引脚46的表面可同样有凹陷部。
于一些实施例中，第一印刷电路板70的第一表面700的面积和第一印刷电路板70的第二表面701的面积相同，第一磁芯20的第一表面200的面积和第二磁芯21的第二表面210的面积相同，且第一印刷电路板70的第二表面701的面积小于等于1.5倍第二磁芯21的第二表面210的面积，当第一印刷电路板70邻设于第二磁芯21时，第一印刷电路板70的第二表面701和第二磁芯21的第二表面210相互重叠的部分至少占第一印刷电路板70的第二表面701的面积的70％或第二磁芯21的第二表面210的面积的70％，当第一印刷电路板70邻设于第一磁芯20时，第一印刷电路板70的第二表面701和第一磁芯20的第一表面200相互重叠的部分至少占第一印刷电路板70的第二表面701的面积的70％或第一磁芯20的第一表面200的面积的70％。
请再参阅图4，于一些实施例中，第二印刷电路板3除了包含第一绕组30外，还包含至少一辅助绕组33及至少一屏蔽结构34，其中每一辅助绕组33及每一屏蔽结构34的设置位置可为第二印刷电路板3内的任意一层或多层的空间处，不局限于设置如图4所示的位置，其中辅助绕组33与第一绕组30共同为平面变压器1的初级侧绕组或是次级侧绕组，且辅助绕组33可做为电路的控制信号线，此外，辅助绕组33的线径小于或等于第一绕组30的线径。屏蔽结构34为金属导体结构，用以抑制EMI电磁干扰。于一些实施例中，第二印刷电路板3的至少一层包含第一绕组30，另外，第二印刷电路板3的每一层可包含第一绕组30、辅助绕组33及屏蔽结构34三者中的至少一种。
于一些实施例中，在电源电路组件7及平面变压器1两者之间以乐高积木的堆叠方式进行组合后，可利用灌封(potting)方式将树脂覆盖电源电路组件7及平面变压器1的至少部分，以进行封装，借此提升电源装置1A的安规强度。于其他实施中，导体5(即第一导电引脚)与第二导电引脚46可分别部分暴露于灌封的树脂而外露至少部分，借此导体5与第二导电引脚46可插设于系统板上。
于一些实施例中，如图2所示，电源装置1A还包含中空盖体8，用以容置组合后的电源电路组件7及平面变压器1，借此保护电源装置1A的内部元件。
于其他实施例中，电源装置1A可改为包含两个电源电路组件，分别设置于电源装置1A的两相对外侧，两个电源电路组件其中的一电源电路组件的第一印刷电路板70与第二磁芯21相邻设，两个电源电路组件其中的另一电源电路组件的第一印刷电路板与第一磁芯20相邻设。
请参阅图5，其为图2所示的平面变压器的第二绕组的一变化例的结构示意图。于一些实施例中，如图5所示，至少一第二导电引脚46可包含第一弯折部460及第二弯折部461。第一弯折部460连接于第二绕组40对应的端部及第二弯折部461之间，且至少部分设置于第二脚座区45内，此外，第一弯折部460是由第二绕组40的一端部至少弯折一次而形成。第二弯折部461至少部分外露于第二脚座区45的第二上表面或第二下表面而朝 垂直第二脚座区45的方向延伸，且第二弯折部461是由第一弯折部460的一端部弯折一次而形成，使第二弯折部461于弯折处会包含U型结构462，通过U型结构462的形成，可增加第二绕组40整体的引线长度。
当然，参酌前述的内容可知，本公开的平面变压器的印刷电路板的个数及绕组模块的个数实可依实际需求任意变化，例如包含两个绕组模块及一个印刷电路板。
请参阅图6，其为本公开第二优选实施例的电源装置的组合结构示意图。本实施例的电源装置1B与图1所示的电源装置1A的结构相似，且相同的元件标号代表相同的元件、结构与功能，于此不再赘述。而相较于图1所示的电源装置1A的电源电路组件7位于电源装置1A的最外侧，本实施例的电源装置1B的电源电路组件7设置于磁芯组件2的第一磁芯20及第二磁芯21之间，因此第一印刷电路板70与第一磁芯20及第二磁芯21分别相邻设。
综上所述，本公开为一种电源装置，电源装置包含了电源电路组件及平面变压器，且电源电路组件及平面变压器两者之间可以像乐高积木般堆叠的方式进行组合，如此一来，由于电源电路组件及平面变压器两者之间为组合结构，故电源装置在生产时无须备齐所有电子元件上线制作组装，即电源电路组件及平面变压器可分别在不同地进行组装后再汇集而构成电源装置，因此电源装置在制作上更为方便。此外，亦由于电源电路组件及平面变压器两者之间可以像乐高积木般堆叠方式的进行组合，故在维修上，电源电路组件及平面变压器可个别进行维修，因此无须对电源装置完全拆除，可提升电源装置内的元件利用率。更甚者，由于平面变压器包含分别为独立元件的第二印刷电路板及绕组模块，其中第二印刷电路板包含第一绕组，绕组模块包含第二绕组，因此平面变压器实将变压器所需的绕组采分离设计而形成第一绕组及第二绕组，并分别位于两个独立元件上，如此一来，平面变压器可因第二绕组位于绕组模块上而减少第二印刷电路板的层数，使第二印刷电路板的层数相较于传统平面变压器的单一电路板的层数少，进而使平面变压器的生产周期较短，且使第二印刷电路板的工艺较低而容错率高，进而减少平面变压器的生产成本，更甚者，本公开的平面变压器的可调性优选。
