8 4 電路說明 LYT4321E (U1) 是一個高度整合的一次側控制器, 設計用於 LED 應用 它可以 Singlestage 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 FR1 可在發生元件故障時提供保護, 並在調光時提供額外阻尼 MOV RV1 會提供箝位以限制線差動電壓突波事件期間的電壓 橋式整流器 BR1 可對 AC 線電壓進行整流 EMI 濾波功能是由電感器 (L2) 及電容器 C6 和 C7 組成的 π 濾波器所提供 4.2 電源電路此設計中所選擇的結構是低壓降壓式轉換器, 設定為在 190 VAC 至 265 VAC 輸入電壓範圍內提供高效率 ( 但小量磁性 ) 低 THD 高功率因數, 以及定電流輸出 電感器 T1 是降壓式轉換器的主要電感器 其包含兩組繞組, 即一次側繞組和偏壓繞組 一次側繞組是主要降壓式電感器 偏壓繞組是 IC 的供應器, 可協助防止在深度調光期間發生的閃爍及閃光 對於雙向閘流器 (TRIAC) 調光, 需要至少 25 V 供應器的偏壓電源供應器 此要求可確保在最小 LED 串電壓下為 IC 提供足夠的電壓, 並且可讓雙向閘流器 (TRIAC) 調光器在最小導通角 ( 小於 30 度 ) 下正常運作 輸出二極體 D7 會在每次 U1 關閉時導通, 讓儲存在 T1 的能量能夠傳輸到負載 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回 U1 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 存在線間弛波時, 電阻器 R12 會成為 C8 的放電路徑, 以使 V 接腳快速回應 線電壓過壓關機功能 ( 透過 V 接腳感測 ) 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 LYTSwitch 的快斷型線間過壓偵測加上搭配使用 D3 和 C8 峰值偵測器電容器, 可提供箝位來限制線間突波期間 IC 的功率 MOSFET 上的最大電壓應力 C8 上值 2.2 µf 可承受 500 V 突波, 而 4.7 µf 則可承受 1 kv 突波 如果需要大於 1 kv 線電壓高壓突波, 可使用其他的 270 VAC 額定 MOV ( 金屬氧化物可變電阻 ) 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 建議使用外部偏壓供電 ( 透過 D9 和 R19) 以提供最低的裝置消耗功率, 並在深度調光情況下, 充裕供電給 U1 選擇的電容器 C10 為 4.7 µf, 因為 LYT4321E 只有一種功率模式 參考, Inc. Page 8 of 41
9 (R) 接腳 (R17) 使用了 24.9 kω 值的電阻器, 同時在 V 接腳上使用 4 MΩ (R13+R14) 電阻, 以便使輸入電壓和輸出電流之間形成線性關係 輸出電容器 C12 是輸出濾波電容器 預載電阻器 R24 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 ) 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 使用偏壓繞組電壓可間接感測輸出電壓, 而不再需要二次側回授元件 偏壓繞組電壓與輸出電壓成正比 ( 由偏壓繞組和一次側繞組之間的圈數比設定 ) 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 R25 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 在啟動期間或短路狀況下, 必須使用二極體 D9 隔離 BP 的電位, 使其不會抑制自動重新啟動功能 電阻器 R19 會限制從偏壓繞組供應給 BP 接腳的電流 U1 的內部引擎會結合 FB 接腳電流 V 接腳電流及內部汲極電流資訊, 以便提供恆定的輸出電流, 同時維持高輸入功率因數 (PF) 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 在設計中採用阻尼器 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 PI 專利主動阻尼器由主要元件 D1 R6 R7 VR1 R9 Q2 C4 Q1 Q2 R3 R4 R5 和 R2 組成 其中 Q2 會在沒有連接 TRIAC 時完全導通, 以繞過 R2, 這將會保持低功率消耗, 進而使系統效率提高 TRIAC 會透過 C2 R3 和 R4 偵測, 這將會短暫地驅動 Q1, 使 C3 接地和 Q2 的閘極維持低值, 以便讓 R2 能與 TRIAC 串接, 在 TRIAC 每次啟動時, 用作阻尼元件 ( 電流振盪 ) 被動洩放器網路由電容器 C1 和電阻器 R1 構成 這個網路會減弱輸入, 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 ( 對於具 Page 9 of 41
10 有高漏電流的 TRIAC 至關重要 ) 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 如果雙向閘流器 (TRIAC) 濾波器電容大到足以提供充沛能量來為 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, 以將 Q3 功率消耗降至最低, Inc.
