10 4 電路說明 LYT4311E (U1) 是一個高度整合的一次側控制器, 主要用於 LED 驅動器應用 它可以 Single-stage 轉換提供高功率因數 (PF), 同時還能在廣泛的輸入範圍 (190 VAC 至 265 VAC) 內調節輸出電流 所有負責這些功能的控制電路, 加上高電壓功率 MOSFET 都整合到 IC 內 4.1 輸入 EMI 濾波 保險絲 F1 可在發生元件故障時提供保護, 而 RV1 可在發生差模線電壓突波活動期間進行箝制, 以限制最大電壓 橋式整流器 BR1 可對 AC 線電壓進行整流 EMI 濾波由電感器 L1 和 L2, 以及電容器 C6 和 C7 提供 在 L1 和 L2 上的電阻器 R10 和 R11 會抑制電感器自身的諧振, 以避免傳導性 EMI 圖中的雜訊在這些電感器的諧振頻率下達到峰值 由於選用的電感器不防磁, 且彼此相鄰串聯連接, 所以在佈局中, 謹慎考量了 L1 與 L2 之間磁耦合的影響, 以產出一致的 EMI 反應 在此設計中,L1 與 L2 垂直接合, 且良好控制了繞組的起始和終止, 並在電路圖和 PCB 中以圓點表示 ( 如需起始和終止繞組的相關資訊, 請參閱電感器製造商產品規格型錄 ) 4.2 電源電路 此設計選用了低端 Tapped Buck, 設定為在 190 VAC 至 265 VAC 輸入電壓範圍內提供低 THD 高功率因數 (PF) 和定電流輸出 Tapped-Buck 轉換器具有下列優勢 : 減小磁性元件的尺寸 主電源切換開關 U1 上的電流應力以及輸出二極體 D7 上的電壓應力 主電源切換開關上的電流應力減小後, 便可使用較小的切換裝置, 以提供更具成本效益的設計 輸出二極體上的電壓應力減小後, 便可使用低 V F ( 蕭特基 ), 以提高效率 電感器 T1 是降壓式轉換器的主要電感器 其包含三組繞組, 即一次側繞組 二次側繞組和偏壓繞組 一次側與二次側圈數比選為 4:1, 這樣便可使用 200 V 輸出二極體, 同時保持 U1 LYT4311E 的最大電壓遠低於其最大值 每當 U1 關閉時, 輸出二極體 D7 就會傳導, 並將能量輸送到負載 需要使用二極體 D5, 才能在 C7 上的電壓 ( 整流後的輸入 AC) 降到低於輸出電壓時防止反向電流流經 U1 還增加了電壓箝位電路, 以限制由 T1 漏電感引起的電壓突波 電壓箝位網路由二極體 D4 電容器 C9 及電阻器 R15 和 R16 構成 選用了輸出電容器 C12 以將輸出漣波降至最低 ( 低於 30%) 預載電阻器 R24 和 R25 會在移除 AC 時將輸出端快速放電至 LED 串電壓以下, 並確保燈具完全熄滅, 而不是在移除 AC 後微弱地發光數秒鐘, Inc. Page 10 of 48
11 為了提供峰值線電壓資訊給 U1, 輸入整流 AC 峰值電壓會透過 D3 為 C8 充電 然後, 該電壓將以透過 R13 和 R14 的電流形式饋送至 U1 的電壓監測器 (V) 接腳 電阻器 R12 提供放電路徑, 可讓 C8 上的電壓追蹤輸入 AC 的變化 線電壓過壓關機功能 ( 透過 V 接腳電流感測 ) 可讓整流後的線電壓耐受度 ( 在突波和線間陡昇期間 ) 提高至內部功率 MOSFET 的 725 BV DSS 額定值 電容器 C10 會為 U1 的 BYPASS (BP) 接腳 ( 內部控制器的供電接腳 ) 提供本機去耦合 在啟動期間, 會從 U1 汲極 (D) 接腳連接的內部高電壓電流源將 C10 充電至約 6 V 選擇的電容器 C10 為 100 F, 可讓裝置在深度調光模式下更好地操作, 否則, 可使用 4.7 uf, 因為 LYT4311 只有一種功率模式 U1 的參考 (R) 接腳透過電阻器 R17 接地 ( 源極 ) 使用 24.9 k 值以提供嚴格的定電流調節 4.3 偏壓電源供應器和輸出回饋 T1 的偏壓繞組用於提供回饋和供電給 IC 偏壓繞組上的返馳式電壓會使用 D8 進行整流 C11 進行濾波, 以使電壓平順, 並使用 R20 減少從漏電感能量耦合的過量電壓 然後回饋電流會透過電阻器 R18 回饋到回饋 (FB) 接腳 二極體 D9 和 R19 會將 BP 接腳連結到偏壓繞組 啟動期間需要使用二極體 D9 來隔離 C10 與 C11, 電阻器 R19 則限制從偏壓繞組供應給 BP 接腳的電流 R21 提供偏壓供電的負載, 以加快 C11 在 AC 週期期間的放電, 並有助於實現較高的調光比 4.4 TRIAC 相位調光控制相容性 為了提供低成本的輸出調光功能, 採用 TRIAC 的前緣和後緣相位調光器在設計時有許多取捨 由於 LED 照明所消耗的功率小得多, 因此燈泡所汲取的電流會低於許多調光器內 TRIAC 的保持電流 (holding current) 這會導致發生不良情況, 例如調光範圍受限及 ( 或 ) 在 TRIAC 啟動時不一致地閃爍 開啟 TRIAC 時,LED 燈相對較大的阻抗會因對輸入電容充電的突波電流 (inrush current) 而導致大幅振盪 這個效應會導致發生閃爍, 因為振盪可能導致 TRIAC 電流降至零並關閉 在設計中整合阻尼器 洩放器和線性調節器電路可以克服這些問題, 而且幾乎不影響驅動器的效率 電阻器 R2 和 R8 提供被動阻尼以及由 D1 R6 R7 C3 VR1 C4 Q2 和 R9 組成的包覆電路, 並藉由在 TRIAC 導通後於線性模式下操作 Q2 約 2 ms, 將 R2 和 R8 的功耗降至最低 電容器 C2 R3 R4 R5 和 Q1 提供放電路徑, 如此一來, 當下一個 TRIAC 切換週期開始時,Q2 一開始就會關閉 所以會選取這些值, 以便在未連接 TRIAC 時, 使 Q2 永久開啟, 以協助提升非調光操作期間的效率 Page 11 of 48
12 被動洩放器網路由電容器 C1 和 R1 構成 這個網路會減弱輸入網路, 但也會為雙向閘流器 (TRIAC) 調光器提供所需的鎖定和保持電流 新增的線性調節器電路 R22 R23 VR2 Q3 和 D10 可持續為 IC (BP 接腳 ) 穩定供電, 可讓此 IC 在非常低的導通角或極低的輸入電壓下正常運作, 並使該 IC 作為負載 ( 尤其是具有高漏電流的 TRIAC) 大多數高額定功率 ( 大於 600 W) 雙向閘流器 (TRIAC) 調光器均具有 LC 輸入濾波器 如 C 大到足以提供能量來為 LED 驅動器的輸入階段充電, 當 LED 負載通電時,LED 便會開啟, 直到輸入放電 然後會重覆此循環, 並導致 LED 負載閃爍, 即使關閉了雙向閘流器 (TRIAC) 也是一樣 當偏壓電壓高於 Vz VR2 +Vt Q3 + Vf D10 時, 將不會啟動線性調節器 選擇電壓調節器 VR2 可讓線性調節器僅在偏壓電壓夠低情況下進行深度調光期間運作, 將 Q3 功率消耗降至最低 MOSFET Q3 可換成 BJT (400V) 以降低成本, 而電阻器 R22 和 R23 則必頇隨之調整, 以提供充沛動力, 尤其輸入電壓在深度調光情況下偏低時, Inc.
