Description

低漣波電源供應器
本發明係關於一種低漣波電源供應器，特別是關於一種完全利用現有電子電路元件所開發製造，低成本容易量產，且具有複數個升壓模組之低漣波電源供應器。
電源供應器對所有電子產品來說，都是一個絕對必要的裝置，其最主要之功能係將輸入至電源供應器的電壓，轉換為直流電壓，供應給相連接之電子產品。電源供應器的種類甚多，主要有交換模式或變壓器模式或整流模式等種類。
然而，現今使用的電源供應器，不管是何種類，卻經常於使用時遭遇到漣波過大的問題，以致形成電子產品操作的不穩定。更有甚者，偶會發生因為電源供應器的漣波過大，而使電子產品產生跳電或毀損的狀況。
因此，在大量提高應用普遍性及有效降低製造與使用成本的前提下，如何提供一個高信賴性、高穩定性、整體體積小，且成本大幅降低的低漣波電源供應器，便成為電源供應器產業，甚至整個電子產品供應漣，一個重要的研究課題。
本發明為一種低漣波電源供應器，其包括一時脈產生器，複數個升壓模組以及一加和單元。本發明之低漣波電源供應器係將時脈產生器所產生複數個相位皆不相同之時脈，分別輸入複數個升壓模組以輸出漣波抵消之直流電壓。再以加和單元將該些升壓模組輸出之直流電壓加總，成為低漣波輸出電壓。
本發明係提供一種低漣波電源供應器，其包括：一時脈產生器，用以輸出複數個時脈訊號，且每一時脈訊號之相位皆不相同；複數個升壓模組，與時脈產生器信號相連接，每一升壓模組係輸入一時脈訊號，又其中每一升壓模組包括有：一第一升壓器，用以輸入時脈訊號，並輸出一第一電壓；一反相器，用以輸入時脈訊號，並將時脈之相位反相後輸出一反相訊號；及一第二升壓器，用以輸入反相訊號，並輸出一第二電壓；以及一加和單元，係輸入及加總每一第一電壓及每一第二電壓，並輸出一輸出電壓。
藉由本發明之實施，至少可以達到下列進步功效：一、使用現有電子裝置，免除額外成本，並減小電路製作複雜度；及二、輸出低漣波輸出電壓，改進現有電源供應器大輸出漣波之缺點。
為了使任何熟習相關技藝者了解本發明之技術內容並據以實施，且根據本說明書所揭露之內容、申請專利範圍及圖式，任何熟習相關技藝者可輕易地理解本發明相關之目的及優點，因此將在實施方式中詳細敘述本發明之詳細特徵以及優點。

第1圖為本發明實施例之一種低漣波電源供應器組成方塊圖；及第2圖為本發明實施例之一種升壓模組方塊圖。
如第1圖所示，為一種低漣波電源供應器100，其包括一時脈產生器10，複數個升壓模組20以及一加和單元30。其中每一升壓模組20又包括一第一升壓器(charge pump)21、一反相器(inverter)22及一第二升壓器23。
如第1圖所示，時脈產生器10，係用以輸出複數個時脈訊號(W1~Wn)，且任二時脈訊號之相位皆不相同。其中時脈產生器10可以為一環式振盪器電路(ROSC，ring oscillator circuit)，每一個時脈訊號係可以自環式振盪器電路之每一個振盪電路階段(oscillator circuit stage)輸出，且時脈訊號之總數係與環式振盪器電路之振盪電路階段之總數相同。
如第1圖及第2圖所示，升壓模組20，係與時脈產生器10信號相連接，每一升壓模組20係輸入一不同相位之時脈訊號。
如第1圖及第2圖所示，每一升壓模組20之第一升壓器21，係用以輸入一時脈訊號，並輸出一第一電壓V1。每一升壓模組20之反相器22，係用以輸入時脈訊號，並將時脈訊號之相 位反相(相位改變180度)後輸出一反相訊號(Wr1~Wrn)。每一升壓模組20之第二升壓器23，係用以輸入一反相訊號，並輸出一第二電壓V2。
如第1圖及第2圖所示，升壓模組20之第一升壓器21輸出之第一電壓V1包含有時脈訊號之漣波或雜訊，而第二升壓器23輸出之第二電壓V2則包含有經過反相的漣波或雜訊，將第一電壓V1與第二電壓V2相加總後，漣波或雜訊因為強度(振幅)相同且相位相反而抵消，因此升壓模組20輸出之電壓，便成為第一電壓V1與第二電壓V2相加總之直流電壓，而無漣波或雜訊。
如第1圖所示，加和單元30，係輸入及加總每一第一電壓V1及每一第二電壓V2，並輸出一輸出電壓Vout，且輸出電壓Vout係為一直流電壓。
如前所述，低漣波電源供應器100係將時脈產生器10所產生複數個相位皆不相同之時脈訊號(W1~Wn)，分別輸入複數個升壓模組20，每一升壓模組20皆將輸入之時脈訊號分為二路，分別輸入第一升壓器21及第二升壓器23，且輸入第二升壓器23之時脈訊號係先經由反相器22進行反相。
在加總第一升壓器21及第二升壓器23輸出的第一電壓V1及第二電壓V2時，由於第一電壓V1及第二電壓V2之漣波的相位相反而可將漣波互相抵消，最後以加和單元30將該些升壓模組20輸出之電壓加總便成為低漣波直流電壓。
惟上述各實施例係用以說明本發明之特點，其目的在使熟習該技術者能瞭解本發明之內容並據以實施，而非限定本發明之專利範圍，故凡其他未脫離本發明所揭示之精神而完成之 等效修飾或修改，仍應包含在以下所述之申請專利範圍中。
