Description

可應用於功率因數校正轉換器的控制電路模組
本發明是有關於一種控制電路模組，且特別是有關於一種可應用於功率因數校正轉換器的控制電路模組。
隨著科技的進步與經濟的發展，人類對切換式轉換器的需求與日俱增。近年來，由於電力電子技術的大幅進步，大部份的電子器材日亦趨向輕薄短小化的方向發展，其內部的電源轉換器亦需朝向輕薄短小的趨勢設計，因此，具有體積小、重量輕、效率高等優點的切換式電源轉換器便逐漸取代傳統線性是轉換器，成為電源轉換器的主流。切換式轉換器除了短小輕薄等優點之外，更近一步提升了轉換器效率及品質。
功率因數修正器(power factor corrector，PFC)常見之操作模式有連續導通模式(continuous conduction mode，CCM)、不連續導通模式(discontinuous conduction mode，DCM)、與邊界導通模式(boundary conduction mode，BCM)等，皆有其各自適合之運用場合。
一般而言，習知的PFC電感電流操作於BCM模式時，當電感電流在左右兩側的谷底時，一般以高頻操作在BCM模式，造成高切換損失而影響效率。然而，目前為避免高切換率而損失的問題，所以本案之發明人提供其解決之方案。
有鑑於此，本發明之目的是提供一種可應用於功率因數校正轉換器的控制電路模組，藉由將電感電流於谷底的操作模式由BCM改操作於DCM，以降低切換頻率而能提高效率。
為達上述或其他目的，本發明提出一種可應用於功率因數校正轉換器的控制電路模組，該控制電路模組與一電感元件耦接，且該電感元件與一輸入電壓端及一輸出電壓端耦接。該控制電路包括有耦接於該電感元件的一電晶體元件，一零電流偵測(ZCD；Zero Current Detection)電路與該電感元件耦接，並可反應出電晶體元件切換於非導通狀態時產生一第一訊號。一栓鎖及計數電路與該電感元件耦接，其可產生一第二訊號，一邏輯判斷電路與該零電流偵測電路及該栓鎖及計數電路耦接以接收該第一訊號及該第二訊號，並產生一第三訊號。一積體電路與該邏輯判斷電路耦接以接收該第三訊號，並產生一閘門訊號傳至該電晶體元件，及一栓鎖解除電路與該積體電路耦接並接收該閘門訊號，並產生一栓鎖解除訊號至該栓鎖及計數電路。其中，該栓鎖及計數電路需達到預設的計數時間而能產生該第二訊號，並藉由接收該栓鎖解除訊號使該栓鎖及計數電路回覆至初始狀態以重新開始計數。
綜上所述，藉由本發明可將電感電流於谷底的操作模式由BCM改操作於DCM，以降低切換頻率而能提高效率。

為讓本發明之上述和其他目的、特徵和優點能更明顯易懂，下文特舉較佳實施例，並配合所附圖式，作詳細說明如下。
請參閱圖1及圖2所示，其為本發明之較佳實施例之電路示意圖及電感電流示意圖。本發明提出一控制電路模組(1)，該控制電路模組(1)與一電感元件耦接(2)，該電感元件(2)與一輸入電壓(3)及一輸出電壓(4)耦接。其中該電感元件(2)可為扼流圈(Chock)組件。
該控制電路模組(1)包括有一電晶體元件(10)、一零電流偵側電路(11)、一栓鎖及計數電路(12)、一邏輯判斷電路(13)、一積體電路(IC)(14)、一栓鎖解除電路(15)以及一補償電路(16)。其中，該電晶體元件(10)可為金氧半場效電晶體(MOSFET)，而該積體電路(14)可為一微處理器(MCU)。
該電晶體元件(10)、該零電流偵側電路(11)及該栓鎖及計數電路(12)分別與該電感元件(2)耦接，其中，該電感元件(2)可反應該電晶體元件(10)處於導通或非導通之狀態，且在該電晶體元件(10)切換於非導通狀態時，該零電流偵側電路(11)可產生一第一訊號。該栓鎖及計數電路(12)需達到預設的計數時間後才能產生一第二訊號，此時即將電感電流的操作 模式由BCM改由DCM。
該邏輯判斷電路(13)與該零電流偵測電路(11)及該栓鎖及計數電路(12)耦接，且當該邏輯判斷電路(13)接收到該第一訊號及該第二訊號時，該邏輯判斷電路(13)即可產生一第三訊號。該第三訊號則將傳送至與該邏輯判斷電路(13)耦接的該積體電路(14)，使該積體電路(14)產生一閘門訊號。
該積體電路(14)與該電晶體元件(10)及該栓鎖解除電路(15)耦接，且該積體電路(14)產生的該閘門訊號分別傳送至該電晶體元件(10)及該栓鎖解除電路(15)，使該電晶體元件(10)可形成導通的狀態，且該栓鎖解除電路(15)可產生一栓鎖解除訊號至該栓鎖及計數電路(12)，使該栓鎖及計數電路(12)回覆至初始狀態以重新開始計數。
前述實施例主要運用於該電晶體元件(10)在谷底時需將電感電流的操作模式由BCM該為DCM，然而當該電晶體元件(10)在波峰時，則需保持維持在BCM的操作模式。該補償電路(16)與該栓鎖及計數電路(12)耦接，當該電晶體元件(10)在波峰時將激發該補償電路而可調整該栓鎖及計數電路(12)的計數時間，使該電晶體元件(10)維持在BCM的操作模式。
雖然本發明已以較佳實施例揭露如上，然其並非用以限定本發明，任何熟習此技藝者，在不脫離本發明之精神和範圍內，當可作些許之更動與潤飾，因此本發明之保護範圍當是後附之申請專利範圍所界定者為準。
