Description

具負載適應性之電源供應器
本創作係關於一種電源供應器，特別是關於一種具負載適應性之電源供應器。
在各種電源轉換器的應用中，對電源轉換效率會有不同的要求。目前已知的能源效率等級可分為白牌、銅牌、銀牌、金牌、白金牌、鈦金牌等五個不同等級，其中，鈦金牌是最高等級，其特別要求在10%負載的情況下的能源效率值要達到規定，而其他四個不同等級都要求在20%、50%、100%的負載條件下要達到規定的能源效率值。
然而，要從極輕載至重載都達到規定的能源效率值並非易事。因此本領域亟需一種新穎的電源供應器結構。
本創作之目的在於揭露一種具負載適應性之電源供應器，其可藉由一數位微控制器單元反應一負載之功率，以依輕載至重載的各種不同負載狀況使一可控橋式整流單元產生不同的導通阻抗，從而提升供電效率並節省能源。
為達前述目的，一種具負載適應性之電源供應器乃被提出，其具有：
一導通阻抗可控橋式整流單元，用以依一交流輸入電壓產生一全波整流輸出電壓以驅動一負載，且該導通阻抗可控橋式整流單元具有至少一控制端，以依至少一控制信號控制其於該交流輸入電壓之正半周和負半周中之至少一半周期間的導通阻抗；
一驅動電路單元，與該導通阻抗可控橋式整流單元耦接，係用以依一脈衝調變信號產生所述至少一控制信號；
一負載功率量測單元，用以量測該負載之功率；以及
一數位微控制器單元，係與該驅動電路單元及該負載功率量測單元耦接，以依該功率決定該脈衝調變信號的占空比以驅動該驅動電路單元，俾以依該功率的不同數值調整該導通阻抗可控橋式整流單元的所述導通阻抗，從而提升所述電源供應器的電源轉換效率。
在一實施例中，該導通阻抗可控橋式整流單元係由四個整流元件構成，至少一所述整流元件係一導通阻抗可控整流元件，且所述導通阻抗可控整流元件係依一所述控制信號控制其導通阻抗。
在一實施例中，所述導通阻抗可控整流元件係由一二極體和一電晶體構成，其中，該二極體的兩端係和該電晶體的通道並聯，且該電晶體的控制端係和一所述控制信號耦接。
在一實施例中，該電晶體係一場效電晶體。
在一實施例中，該數位微控制器單元具有一記憶體單元以儲存一控制程式。
為使 貴審查委員能進一步瞭解本創作之結構、特徵及其目的，茲附以圖式及較佳具體實施例之詳細說明如後。
請參照圖1，其為本創作之具負載適應性之電源供應之一實施例方塊圖。如圖1所示， 該具負載適應性之電源供應器具有一導通阻抗可控橋式整流單元100、一驅動電路單元110、一負載功率量測單元120及一數位微控制器單元130。
導通阻抗可控橋式整流單元100係用以依一交流輸入電壓V AC產生一全波整流輸出電壓V REC以驅動一負載200，且該導通阻抗可控橋式整流單元100具有至少一控制端，以依至少一控制信號SW控制其於該交流輸入電壓V AC之正半周和負半周中之至少一半周期間的導通阻抗。在一實施例中，該導通阻抗可控橋式整流單元100係由四個整流元件(未示於圖1中)構成，且其中至少一所述整流元件係一導通阻抗可控整流元件，亦即，至少一所述整流元件係依一所述控制信號控制其導通阻抗。例如，所述導通阻抗可控整流元件可由一二極體和一電晶體構成，其中，該二極體的兩端係和該電晶體的通道並聯，且該電晶體的控制端係和一所述控制信號SW耦接。在一可能的實施例中，該電晶體可為一場效電晶體或其它三端功率開關。
驅動電路單元110係與該導通阻抗可控橋式整流單元100耦接，且係用以依一脈衝調變信號PWM產生所述至少一控制信號SW。
負載功率量測單元120係用以量測該負載200之功率P L，並將其提供給數位微控制器單元130。
數位微控制器單元130，具有一記憶體單元以儲存一控制程式，係與該驅動電路單元110及該負載功率量測單元120耦接，以依該功率P L決定該脈衝調變信號PWM的占空比以驅動該驅動電路單元110，俾以依該功率P L的不同數值調整該導通阻抗可控橋式整流單元100的所述導通阻抗，從而提升所述電源供應器的電源轉換效率。
由上述可知，藉由前述所揭露的設計，本創作的具負載適應性之電源供應器乃可藉由一數位微控制器單元反應一負載之功率，以依輕載至重載的各種不同負載狀況使一可控橋式整流單元產生不同的導通阻抗，從而提升供電效率並節省能源。
本案所揭示者，乃較佳實施例，舉凡局部之變更或修飾而源於本案之技術思想而為熟習該項技藝之人所易於推知者，俱不脫本案之專利權範疇。
綜上所陳，本案無論就目的、手段與功效，在在顯示其迥異於習知之技術特徵，且其首先創作合於實用，亦在在符合新型之專利要件，懇請 貴審查委員明察，並祈早日賜予專利，俾嘉惠社會，實感德便。
