操作上,充電裝置100用以供電給第一負載裝置202。具體而言,交直流變壓器120用以根據外部交流電源201 提供直流電力訊號至擴充接口單元140。擴充接口單元140用以根據直流電力訊號對第一負載裝置202進行供電。 In operation, the charging

請參考第2圖。第2圖係依據本揭示內容之部分實施例所繪示的一種充電裝置100及其相關連接的細部示意圖。如第2圖所示,於第2圖所示實施例中,與第1圖的實施例中相似的元件係以相同的元件符號表示,其操作已於先前段落說明者,於此不再贅述。和第1圖所示實施例相比,在本實施例中,交直流變壓器120包含交直流轉換單元122及第一降壓單元124。 Please refer to Figure 2. FIG. 2 is a detailed schematic diagram of a
結構上,交直流轉換單元122耦接第一降壓單元124。交直流轉換單元122透過第二傳輸線102耦接外部交流電源201。第一降壓單元124透過第一傳輸線101擴充接口單元140。 Structurally, the AC-
操作上,交直流轉換單元122用以將外部交流電源201轉換成第一直流電源V1。第一降壓單元124用以將第一直流電源V1降壓成第二直流電源V2作為直流電力訊號。 In operation, the AC-
舉例來說,在部分實施例中,第一降壓單元124為變壓器(transformer)或降壓型電源轉換器(buck converter)。值得注意的是,此舉例說明僅作為例示,並非用以限制本案。 For example, in some embodiments, the first step-down
請參考第3圖,第3圖係依據本揭示內容之其他部分實施例所繪示的一種充電裝置100及其相關連接的細部示意圖。如第3圖所示,於第3圖所示實施例中,與第1圖的實施例中相似的元件係以相同的元件符號表示,其操作已於先前段落說明者,於此不再贅述。和第1圖所示實施例相比,在本實施例中,擴充接口單元140包含擴充介面148。在部分實施例中,擴充接口單元140更包含脈衝寬度調變單元141、控制電路142、背對背電晶體單元143及/或第二降壓單元144。在其他部分實施例中,擴充接口單元140更包含匯流排介面147,其中匯流排介面147包含電力傳輸腳位147a、資料腳位147b和控制訊號腳位147c。 Please refer to FIG. 3, which is a detailed schematic diagram of a
在部分實施例中,擴充介面148用以選擇性連接第二負載裝置203。具體而言,擴充介面148可包含通用串列匯流排介面146或影音傳輸介面145。第二負載裝置203可包含擴充電子裝置203a或顯示螢幕203b。舉例來說,通用串列匯流排介面146用以選擇性地連接擴充電子裝置203a。影音傳輸介面145用以選擇性地連接顯示螢幕203b。值得注意的是,此舉例說明僅作為例示,並非用以限制本案。於其他實施例中,擴充介面148也可以包含其他的連接介面,例如一或多個高畫質多媒體介面、視訊圖形陣列、數位視訊介面、顯示埠、通用 序列匯流排Type-A/Type-B/Type-C、網路連接埠、直流電源插孔、耳機插孔及/或喇叭插孔。 In some embodiments, the
於一些實施例中,為了達到輕量化或是薄型化設計,第一負載裝置202可能僅具有少數的連接接口,例如僅包含單一個通用序列匯流排接口,在此情況下第一負載裝置202連接傳統的電源供應裝置進行充電,便無法同時連接至其他的擴充裝置,例如滑鼠、鍵盤、外部螢幕、讀卡機或光碟機等。於此實施例中,透過充電裝置100可以對第一負載裝置202提供電力,並且利用擴充接口單元140可以讓第一負載裝置202在充電的同時一併連接到不同的擴充元件(例如第3圖的第二負載裝置203)。 In some embodiments, in order to achieve a lightweight or thin design, the
一般來說,當擴充元件(例如第3圖的第二負載裝置203中的擴充電子裝置203a或顯示螢幕203b)運作時會需要消耗一定的功率,例如需要供電給擴充電子裝置203a(如滑鼠或外接鍵盤等)以及顯示螢幕203b。在部分實施例中,擴充介面148具有第一額定功率,對應上述擴充元件可能需要的電力消耗。第一負載裝置202具有第二額定功率,對應第二負載裝置203所需的電力消耗。交直流變壓器120所輸出的直流電力訊號V2之輸出功率設置為大於等於第一額定功率與第二額定功率之和。 Generally speaking, when an expansion component (such as the expansion
具體而言,交直流變壓器120係同時考量擴充接口單元140電力和驅動需求以及第一負載裝置202充電或電力需求。舉例來說,若第一負載裝置202需要65W,擴充接口單元140及/或第二負載裝置203需要30W,則交直流變壓器120 將滿足65W+30W=95W的規格。 Specifically, the AC-
此外,由於交直流變壓器120的規格係經過與欲搭配之第一負載裝置202測試驗證通過的生產製造流程,針對第一負載裝置202的效能設計,因此可發揮第一負載裝置202的最大效能。例如,充電速度、資料傳輸速度、影像解析度及/或網路傳輸速度等等。 In addition, since the specifications of the AC-
換言之,由於交直流變壓器120係與第一負載裝置202互相搭配的,因此不會產生交直流變壓器120供電規格不足的問題,亦不會產生對第一負載裝置202供電不足的問題。此外,由於交直流變壓器120可考量到擴充接口單元140電力和驅動需求,因此連接於擴充接口單元140的一或多個第二負載裝置203不會有匹配性問題、效能問題、電力問題等等。 In other words, since the AC-
請繼續參考第3圖。如第3圖所示,結構上,擴充接口單元140透過匯流排介面147耦接第一負載裝置202。脈衝寬度調變單元141耦接交直流變壓器120、控制電路142、背對背電晶體單元143和第二降壓單元144。背對背電晶體單元143耦接匯流排介面147中的電力傳輸腳位147a。控制電路142耦接第二降壓單元144和匯流排介面147中的控制訊號腳位147c。擴充介面148耦接第二降壓單元144和匯流排介面147中的資料腳位147b。 Please continue to refer to Figure 3. As shown in FIG. 3, in structure, the
操作上,脈衝寬度調變單元141用以將直流電力訊號V2調變為第三直流電源V3。背對背電晶體單元143用以將第三直流電源V3轉換為第四直流電源V4輸出給第一負載裝置202。第二降壓單元144用以將第三直流電源V3轉換為第五 直流電源V5並輸出給第二負載裝置203。控制電路142用以決定脈衝寬度調變單元141之工作週期(Duty Cycle),並控制第二降壓單元144輸出之第五直流電源V5之輸出電壓。具體而言,控制電路142用以根據控制訊號腳位147c所接收到的訊號決定脈衝寬度調變單元141之工作週期並控制第二降壓單元144輸出之第五直流電源V5之輸出電壓。換言之,控制電路142透過控制訊號腳位147c偵測電力需求狀況以回饋控制脈衝寬度調變單元141和第二降壓單元144。 In operation, the pulse
此外,在部分實施例中,當擴充介面148空接時,第二降壓單元144停止提供輸出電流至擴充介面148。於一實施例中,由於擴充介面148並未連接任何第二負載裝置203,擴充介面148未連接負載裝置時不會形成供電迴路,此時,第二降壓單元144不再供應輸出電流至擴充介面148。於部分實施例中,當擴充介面148空接時,第二降壓單元144仍可產生直流電壓但不提供輸出電流,於另一些實施例中,當擴充介面148空接時,第二降壓單元144不產生直流電壓。 In addition, in some embodiments, when the
如此一來,連接負載多寡、負載電力需求、負載是否完成充電及/或是否因電阻等其他因素使得直流電壓下降等問題,可由擴充接口單元140進行偵測並補償。 In this way, problems such as the number of connected loads, load power requirements, whether the load is fully charged, and/or whether the DC voltage drops due to resistance and other factors can be detected and compensated by the
請參考第4圖。第4圖係依據本揭示內容之其他部分實施例所繪示的一種充電裝置100及其相關連接的外觀示意圖。於第4圖所示實施例中,與第1圖、第2圖、第3圖的實施例中相似的元件係以相同的元件符號表示,其操作已於先前段落說明者,於此不再贅述。在本實施例中,交直流變壓器120、 第一傳輸線101與擴充接口單元140為一體成形。 Please refer to Figure 4. FIG. 4 is a schematic diagram showing the appearance of a
在部分實施例中,第二傳輸線102與交直流變壓器120之間為固定的。在其他部分實施例中,第二傳輸線102與交直流變壓器120之間為可拆卸的。 In some embodiments, the
在部分實施例中,第三傳輸線103與擴充接口單元140之間為固定的。在其他部分實施例中,第三傳輸線103與擴充接口單元140之間為可拆卸的。 In some embodiments, the
舉例來說,第一傳輸線101可為直流線,可包含電壓選擇控制訊號線。第二傳輸線102可為交流電線。第三傳輸線103可為Type C線,可包含資料線、影像線、控制訊號線及/或電力線,其中影像線可包含數位影像線或類比影像線。進一步說明,第三傳輸線103連接第一負載裝置202的介面可為通用序列匯流排(Universal Serial Bus,USB)、2或4路差分資料連接器(DisplayPort 2 Lanes/DisplayPort 4 Lanes)。值得注意的是,此舉例說明僅作為例示,並非用以限制本案。 For example, the
另外,在部分實施例中,第一傳輸線101的線路長度長於第二傳輸線102的線路長度。第一傳輸線101的線路長度長於第三傳輸線103的線路長度。舉例來說,第二傳輸線102的線路長度可以與傳統連接變壓器之交流電線的線路長度相近,使得交直流變壓器120可放置於靠近外部交流電源201,無需放置靠近於使用者或第一負載裝置202。 In addition, in some embodiments, the line length of the
再者,第三傳輸線103的線路長度亦可與傳統直流充電線的線路程度相近,使得維持製作成本且不影響資料、 影像傳輸速度。也使得擴充接口單元140可放置於靠近使用者或第一負載裝置202,提升使用上插拔第二負載裝置203的便利性。另外,第一傳輸線101的線路長度可依據實際需求進行調整,補足整體所需線路長度。 Furthermore, the line length of the
交直流變壓器120與外部交流電源201(例如市電插座)之間的第二傳輸線102需要乘載外部交流電源,通常外部交流電源的電力規格可能是100伏特至240伏特,因此第二傳輸線102為了符合安全規範需要具有較粗的線徑以及較重的線路重量。於本實施例中,第二傳輸線102的線路長度短於第一傳輸線101的線路長度,因此通常較粗且較難以收納的第二傳輸線102可維持一般長度或較為縮短,不會增加整體攜帶的重量。 The
綜上所述,在本揭示內容的檢測電路中,藉由整合交直流變壓器、擴充接口和連接線,可滿足不同連接負載的電力需求,且不影響各個連接負載的最大效能。 In summary, in the detection circuit of the present disclosure, by integrating the AC-DC transformer, the expansion interface and the connecting line, the power requirements of different connected loads can be met without affecting the maximum performance of each connected load.
