Description
本發明係有關於一種電源供應裝置,特別係有關於一種藉由乙太網路線進行供電之電源供應裝置。The present invention relates to a power supply device, and particularly relates to a power supply device that supplies power through an Ethernet cable.
目前市面上的產品大多因為電源供應裝置(Power Source Equipment)與負載裝置(Power Device)做全時的交握訊號溝通,來判斷電源供應裝置是否應該對負載裝置進行供電,因此即使負載裝置並未耦接至電源供應裝置的情況下,電源供應裝置仍會持續送出交握訊號做偵測而造成電力損耗,並使得目前乙太網路之電源供應裝置無法達到現行效率能源規章的要求,如:美國的能源部(Department of Energy,DoE)、歐洲的符合性證書(EC certificate of conformity,EC CoC)等等。Most of the products on the market at present are because the power supply device (Power Source Equipment) and the load device (Power Device) do full-time handshaking signal communication to determine whether the power supply device should supply power to the load device. Therefore, even if the load device is not When coupled to a power supply device, the power supply device will continue to send handshake signals for detection, causing power loss, and making the current Ethernet power supply devices unable to meet the requirements of current efficiency energy regulations, such as: The Department of Energy (DoE) in the United States, the EC certificate of conformity (EC CoC) in Europe, and so on.
為了降低在無負載下的消耗功率而符合目前效率能源規章的要求,有必要針對電源供應裝置及其控制方法進行最佳化。In order to reduce the power consumption under no load and meet the requirements of current efficiency energy regulations, it is necessary to optimize the power supply device and its control method.
有鑑於此,本發明提出一種耦接至一電力裝置之電源供應裝置,包括:一輸出連接埠及一控制器。上述輸出連接埠用以耦接至一連接線。當上述連接線耦接至上述輸出連接埠時,上述控制器被啟動以產生一交握信號,以跟上述電力裝置進行通訊。當透過上述交握信號判斷上述電力裝置係可供電之對象時,上述控制器控制上述電源供應裝置經由上述連接線對上述電力裝置進行供電。當上述連接線未耦接至上述輸出連接埠時,上述控制器被禁能且不產生上述交握信號。In view of this, the present invention proposes a power supply device coupled to a power device, including: an output port and a controller. The output port is used for coupling to a connection line. When the connection line is coupled to the output port, the controller is activated to generate a handshaking signal to communicate with the power device. When it is determined through the handshake signal that the power device is an object capable of supplying power, the controller controls the power supply device to supply power to the power device via the connection line.

第1圖係顯示根據本發明之一實施例所述之電源供應裝置之方塊圖。如第1圖所示,電源供應裝置100包括電源轉換器110、控制器120、輸入連接埠130、資料整合單元140、輸出連接埠150以及觸發單元160。在本實施例中,當電力裝置10透過連接線170(例如,乙太網路線)連接至電源供應裝置100時,電源供應裝置100不僅可將從輸入連接埠130接收到的資料經由連接線170傳送給電力裝置10,還可藉由外部接收的電壓(例如,市電)經由電源轉換器110同時經由連接線170對電力裝置10進行供電。FIG. 1 shows a block diagram of a power supply device according to an embodiment of the invention. As shown in FIG. 1, the
具體來說,當電力裝置10透過連接線170連接至電源供應裝置100的輸出連接埠150時,控制器120會產生交握信號HS並將交握信號HS經由連接線170傳送給電力裝置10以進行溝通,藉此判斷電力裝置10是否為符合規範的電力裝置。若判斷電力裝置10符合規範時,此時控制器120可經由溝通的過程中判斷電力裝置10所需求的功率/電流(例如,透過電流訊號判斷要給電力裝置10多少功率),並允許電源供應裝置100對電力裝置10進行供電。由於供電的協定已建立,控制器120不需要再跟電力裝置10進行溝通,因此此時便會停止產生交握信號HS。若判斷電力裝置10不符合規範,則控制器120便會禁止電源供應裝置100對電力裝置10進行供電,並持續周期性地發送交握信號HS進行確認。Specifically, when the
另一方面,當電力裝置10並未連接至電源供應裝置100的輸出連接埠150時,在習知的作法中,控制器120仍會持續周期性地產生及發送交握信號HS以確認電力裝置10是否已經連接電源供應裝置100。然而,這樣的作法會導致在電源供應裝置100即使在電力裝置10沒連接的情況下,控制器120仍然會持續消耗電力去產生交握信號HS以進行確認的操作。On the other hand, when the
由於習知的作法會衍生出電源供應裝置100未連接電力裝置10時電源供應裝置100仍然會有功耗的問題。在本實施例中,當電源供應裝置100未連接電力裝置10時,控制器120不會啟動,亦不會產生交握信號HS,以達到降低無載時電源供應裝置100的功率損耗,進而符合的效率能源規章的要求,其具體實施方式將說明如下。Since the conventional practice will derive the problem that the
根據本發明之一實施例,電源供應裝置100係為符合IEEE 802.3 at之乙太網路供電(Power over Ethernet, PoE)的規範。根據本發明之另一實施例,電源供應裝置100係為符合IEEE 802.3 af之乙太網路供電的規範。根據本發明之再一實施例,電源供應裝置100係為符合IEEE 802.3 bt之乙太網路供電的規範。According to an embodiment of the present invention, the
在本實施例中,電源轉換器110用以將外部電壓VEXT(例如,市電)轉換成供應電壓VDD。在一些實施例中,電源轉換器110可為交流/直流轉換器,用以將市電提供的交流電壓轉換為直流電壓,此直流電壓可對電源供應裝置100裡的元件(例如,控制器120)及/或電源供應裝置100外的裝置(例如,電力裝置10)進行供電。In this embodiment, the
控制器120經觸發之觸發單元160(具體細節將於之後敘述)而接收供應電壓VDD之供電,並產生交握信號HS。根據本發明之一實施例,當控制器120透過交握信號HS確認電力裝置10係為可供電之對象(亦即,電力裝置10符合乙太網路供電的規範)時,控制器120停止發送交握信號HS。另外,此時控制器120可透過與電力裝置10進行溝通的過程得知電力裝置10的負載情況,並控制電源轉換器110轉換外部電壓VEXT以提供電力裝置10所需之電壓/電流,經轉換之電壓/電流可經由資料整合單元140、輸出連接埠150以及連接線170提供給電力裝置10進行供電。The
根據本發明之另一實施例,當控制器120透過交握信號HS確認電力裝置10非為可供電之對象(亦即,電力裝置10不符合乙太網路供電的規範)時,控制器120控制電源供應裝置100不對電力裝置10進行供電,並持續周期性地發送交握信號HS以確認電力裝置10的情況。According to another embodiment of the present invention, when the
輸入連接埠130接收外部資料DEXT並將外部資料DEXT傳送給資料整合單元140。。當控制器120透過交握信號HS確認電力裝置10係為可供電之對象時,資料整合單元140可將外部資料DEXT經由輸出連接埠150和連接線170傳輸至電力裝置10。The input port 130 receives the external data DEXT and transmits the external data DEXT to the
輸出連接埠150用以耦接至連接線170,其中連接線170具有耦接至輸出連接埠150之連接頭(第1圖中並未顯示)。根據本發明之一實施例,輸出連接埠150可為接收RJ-45接頭之插座,連接線170係為具有RJ-45接頭之網路線。當輸出連接埠150耦接至連接線時,代表輸出連接埠150容置網路線之RJ-45接頭。The output connection port 150 is used to couple to the
在本實施例中,電源供應裝置100還包括觸發單元160,其用以在連接線170耦接至輸出連接埠150的情況下觸發。根據本發明之一實施例,當觸發單元160觸發時,電源轉換器110輸出的供應電壓VDD可經由觸發單元160直接提供給控制器120,藉以對控制器120進行供電以啟動控制器120,使得控制器120發出交握信號HS以跟電力裝置10相互進行通訊。根據本發明之另一實施例,當觸發單元160並未觸發時,供應電壓VDD不對控制器120進行供電,因此控制器120不發出交握信號HS,以節省電源供應裝置100之電源消耗,進而符合效率能源規章的要求。根據本發明之一實施例,為了更精準的偵測連接線170之連接頭是否插入輸出連接埠150,觸發單元160係位於輸出連接埠150之中。In this embodiment, the
在一實施例中,觸發單元160包含第一連接部161和第二連接部162,其中在未對第一連接部161施力的情況下,第一連接部161與第二連接部162係電性隔絕(亦即,觸發單元160未被觸發),而在對第一連接部161施力的情況下,第一連接部161可移動地與第二連接部接觸形成電性連接(亦即,觸發單元160被觸發)。具體來說,當連接線170未與輸出連接埠150耦接時,第一連接部161不會受到任何作用力而維持現狀,並與第二連接部162係電性隔絕,使得供應電壓VDD無法經由觸發單元160提供給控制器120,致使禁能控制器120。當連接線170與輸出連接埠150耦接時,第一連接部161受到連接線170之一端(例如連接頭)抵接和推擠的作用力,造成位移並最終與第二連接部162接觸而形成電性連接,使得供應電壓VDD可經由觸發單元160提供給控制器120,致使啟動控制器120。以下將進一步說明觸發單元160的具體實施方式。In one embodiment, the
第2圖係顯示根據本發明之一實施例所述之觸發單元之示意圖。如第2圖所示,觸發單元200包括彈片210(亦即,第1圖的第一連接部161)以及金屬接點220(亦即,第1圖的第二連接部162),其中彈片210係耦接至接收供應電壓VDD之節點(例如,電源轉換器110之輸出端),金屬接點220係耦接至第1圖之控制器120。根據本發明之一實施例,觸發單元200係對應至第1圖之觸發單元160。FIG. 2 is a schematic diagram of the trigger unit according to an embodiment of the invention. As shown in Figure 2, the
第3圖係顯示根據本發明之一實施例所述之輸出連接埠之示意圖。如第3圖所示,輸出連接埠310用以容置連接線之連接頭320。根據本發明之一實施例,連接線用以耦接至第1圖之電源供應裝置100以及電力裝置10,輸出連接埠310係對應至第1圖之輸出連接埠150。根據本發明之一實施例,觸發單元200係位於輸出連接埠310中。FIG. 3 is a schematic diagram showing the output port according to an embodiment of the present invention. As shown in FIG. 3, the
根據本發明之一實施例,當連接頭320插入輸出連接埠310(亦即,連接頭320依插入方向D而插入輸出連接埠310)時,連接頭320抵接彈片210使彈片210作動(例如,下壓),使得彈片210直接接觸金屬接點220(亦即,使得彈片210電性連接於金屬接點220)。在本實施例中,使彈片210電性連接於金屬接點220即意指著觸發單元200被觸發。換句話說,當連接頭320插入輸出連接埠310時,彈片210與金屬接點220電性連接,供應電壓VDD係透過彈片210以及金屬接點220而對控制器120進行供電,使得控制器120啟動並發出交握信號HS與經由連接線170連接之電力裝置10進行溝通,藉以決定是否對電力裝置10進行供電。According to an embodiment of the present invention, when the
根據本發明之另一實施例,當連接頭320並未插入輸出連接埠310時,彈片210以及金屬接點220之間係為電性隔絕。在本實施例中,使彈片210與金屬接點220電性隔絕(或是未電性連接)即意指著觸發單元200未被觸發。因此,此時控制器120無法接收供應電壓VDD而啟動,進而不會產生交握信號HS與電力裝置進行溝通,藉此降低電源供應裝置100在無載情況(亦即,未與電力裝置10連接)下之功率損耗。According to another embodiment of the present invention, when the
值得一提的是,本實施例中的觸發單元包括彈片以及金屬接點等機械之結構而沒有其他電路元件,其是否被觸發係由物理操作決定。換言之,在本發明之實施例中,判斷連接線是否耦接輸出連接埠(亦即,連接頭是否插入輸出連接埠)並非透過電性偵測,舉例來說,透過電源供應裝置裡的元件發出信號(例如,電流),並根據是否接收到對應之回傳信號(例如,另一電流)來判斷連接線是否耦接輸出連接埠。取而代之,本實施例中的觸發單元係完全透過物理性偵測,藉由連接頭插入輸出連接埠時,使彈片與連接頭連動並最終與金屬接點接觸,進而判斷連接頭已完全插入輸出連接埠(亦即,連接線已經耦接輸出連接埠)。這樣做法的優點在於判斷可以快速又準確,且其設置的成本低。It is worth mentioning that the trigger unit in this embodiment includes mechanical structures such as elastic sheets and metal contacts without other circuit elements, and whether it is triggered is determined by physical operations. In other words, in the embodiment of the present invention, determining whether the cable is coupled to the output port (that is, whether the connector is inserted into the output port) is not detected through electrical detection, for example, through a component in the power supply device. Signal (for example, current), and determine whether the connection line is coupled to the output port according to whether the corresponding return signal (for example, another current) is received. Instead, the trigger unit in this embodiment is completely physically detected. When the connector is inserted into the output port, the shrapnel is connected to the connector and finally contacts the metal contact, and then it is determined that the connector is fully inserted into the output connection. Port (that is, the cable has been coupled to the output port). The advantage of this approach is that the judgment can be fast and accurate, and the cost of its setting is low.
然而,本發明並不限於此。在其他實施例中,亦可透過其他偵測元件來判斷連接線是否耦接於輸出連接埠,其將說明如下。However, the present invention is not limited to this. In other embodiments, other detecting elements can also be used to determine whether the connection line is coupled to the output port, which will be described as follows.
第4圖係顯示根據本發明之另一實施例所述之電源供應裝置之方塊圖。將電源供應裝置400與第1圖之電源供應裝置100相比,第1圖之觸發單元160係替換為第4圖之偵測單元460,其餘元件皆相同。FIG. 4 is a block diagram of the power supply device according to another embodiment of the present invention. Comparing the
偵測單元460用以判斷連接線170是否耦接至輸出連接埠150,而決定是否將供應電壓VDD提供至控制器120使其產生交握信號HS。根據本發明之一實施例,當偵測單元460判斷連接線170係耦接至輸出連接埠150時,偵測單元160將供應電壓VDD提供至控制器120而對控制器120供電,並由控制器120發出交握信號HS與電力裝置10進行通訊。根據本發明之一實施例,為了更精準的偵測是否連接線170之連接頭是否插入輸出連接埠150,偵測單元460係位於輸出連接埠150之中。The detecting
根據本發明之另一實施例,當偵測單元460判斷連接線170並未耦接至輸出連接埠150時,偵測單元460不將供應電壓VDD提供至控制器120,以禁能控制器120,達到節省電源供應裝置400之電源消耗,進而符合效率能源規章的要求。According to another embodiment of the present invention, when the detecting

根據本發明之一實施例,當連接線170之連接頭50插入輸出連接埠150而位於光源510以及光線感測器520之間時,連接頭50阻隔了光源510所產生的光束L,使得光線感測器520偵測不到光束L而將第一光線節點521電性耦接至第二光線節點522。亦即,此時光線感測器520將供應電壓VDD提供至控制器120,使得控制器120發出交握信號HS以對電力裝置10進行通訊。According to an embodiment of the present invention, when the connector 50 of the
根據本發明之另一實施例,當連接頭50並未插入輸出連接埠310時,光線感測器520偵測到光束L而將第一光線節點521以及第二光線節點522予以電性分離,亦即,光線感測器520不將供應電壓VDD提供至控制器120,使得控制器120不會產生交握信號HS,以降低電源供應裝置400無載情況下之功率損耗。According to another embodiment of the present invention, when the connector 50 is not inserted into the

根據本發明之一實施例,當連接線170之連接頭60插入輸出連接埠150而位於磁場產生器610以及磁場接收器620之間時,連接頭60阻隔了磁場產生器610所產生的磁場M,使得磁場接收器620偵測不到磁場M而將第一磁場節點621電性耦接至第二磁場節點622。亦即,此時磁場接收器620將供應電壓VDD提供至控制器120,使得控制器120發出交握信號HS以對電力裝置10進行通訊。According to an embodiment of the present invention, when the
根據本發明之另一實施例,當連接頭60並未插入輸出連接埠150時,磁場接收器620偵測到磁場M而將第一磁場節點621以及第二磁場節點622予以電性分離,亦即,磁場接收器620不將供應電壓VDD提供至控制器120,使得控制器120不會產生交握信號HS,以降低電源供應裝置400無載情況下之功率損耗。According to another embodiment of the present invention, when the
透過判斷連接線之連接頭是否插入輸出連接埠而決定是否啟動控制器,進而決定是否要產生交握信號對電力裝置進行溝通,可有效的降低無載時電源供應裝置的功率損耗,進而符合日益嚴苛的效率能源規章的要求。另外,本發明判斷連接線之連接頭是否插入輸出連接埠的實施手段係為物理性操作。換言之,判斷連接線是否耦接輸出連接埠(亦即,連接頭是否插入輸出連接埠)並非透過電性偵測,而是透過物理性偵測,藉由連接頭插入輸出連接埠時,使彈片與連接頭連動並最終與金屬接點接觸,進而判斷連接頭已完全插入輸出連接埠(亦即,連接線已經耦接輸出連接埠)。這樣做法的優點在於判斷可以快速又準確,且其設置的成本低。Determine whether to activate the controller by judging whether the connector of the cable is inserted into the output port, and then determine whether to generate a handshake signal to communicate with the power device, which can effectively reduce the power loss of the power supply device when there is no load, thereby complying with the increasing Strict energy efficiency requirements. In addition, the implementation method of the present invention to determine whether the connector of the connection line is inserted into the output port is a physical operation. In other words, judging whether the cable is coupled to the output port (that is, whether the connector is inserted into the output port) is not through electrical detection, but through physical detection. When the connector is inserted into the output port, the shrapnel Linked with the connector and finally contacted with the metal contact, it is determined that the connector has been fully inserted into the output port (that is, the cable has been coupled to the output port). The advantage of this approach is that the judgment can be fast and accurate, and the cost of its setting is low.
