title="氙氣燈">氙氣燈正在汽車車燈領域興起，與傳統鹵素燈相比，HID 氙氣燈具有節能、亮度高、壽命長、安全可靠、色溫與太陽光類似等優點。HID 氙氣燈由安定器和燈泡構成，安定器是氙氣燈產品的核心部件，氙氣燈的性能與安定器密切相關。隨著HID 安定器技術不斷成熟，新的數字化控制方式也在沖擊著這個行業。

??? 世強電訊根據國內HID 市場的特點需要推出了基于Silicon Labs MCU 的單芯片氙氣燈全數字智能安定器解決方案。該方案采用全數字控制，符合目前數字化的發展潮流。單芯片的控制技術可使出廠調試的工作量大大減少。此外，采用了多項專利技術來提高HID 安定器的性能，包括豐富的故障檢測、高性能的環路響應、展頻特性等。“而這些特性在模擬方案或采用MCU+3843 的方案中都是無法實現的。”深圳世強電訊有限公司應用工程師經理戈洪凱表示。

??? 這款HID 安定器解決方案的特點包括：全數字控制使保護功能更加完善；MCU 控制每一個過程的細節，能更好滿足燈的特性需求；變頻控制使EMI 降到最低，同時減少EMI 元件數量；結合硬件進行算法優化，采用多項專利技術完善對HID 的過程控制和限流保護處理；全數字設計使整個方案基本非常好的可擴展性，可以快速滿足特殊需求的定制開發；采用平面變壓器等技術，有效降低安定器厚度和體積；支持正驅動和負啟動形式，適應各種不同電路方案的安定器；高壓包可采用分體和內置輸出，低壓線引出，高壓線短，安裝方便體積明顯減小許多；CPU 可以選用電可擦寫芯片；保密性強，有利于知識產權保護。

??? 世強的方案采用高性能的MCU 實現HID 控制功能，該器件實現了整套的控制算法，包括DC/DC，DC/AC，保護功能等。整個方案由MCU、驅動及功率元件構成，結構非常簡單，且所有元件都經過優化設計，因而具有良好的性價比。高集成度使元件的數量和面積得到減少，大量采用貼裝元件實現了良好的散熱設計和超薄設計。良好的供電拓撲結構和元件參數則使方案能夠支持寬工作電壓。
