6.1 結論

本論文一共實現出兩種不同架構之複金屬燈電子安定器:

一.傳統式電路拓樸:

1.功率因數修正器 2.降壓式轉換器 3.全橋式變流器 4.類比回授控制電路

二.兩級式電路拓樸:

1.功率因數修正器

2.直流至交流之降壓型轉換器 3.數位控制器

其中兩種電路架構的共同點為使用相同的主動式功因修正電源供 應電路、高壓點火電路以及採用低頻方波電流來解決音頻共振的問題。

但是最大的不同點乃是針對電路的體積與元件使用上的減少作修改,因 此將降壓型轉換器與全橋式變流器合併為非對稱半橋式直流至交流降

壓型轉換器,並且使用數位控制器作為整體電路上時序控制的啟動電 路,因此在整體電路體積上將能有效地的縮小,而且整體電路效能也因 為使用元件的減少使得整體可靠度與電路效能也隨著提高。

6.2 未來展望

為了讓使用者能夠安裝容易與攜帶方便,將整體電路體積再輕量化 與縮小化來說是一項很重要的設計方向,因此複金屬燈電子安定器能夠 在更進一步的縮小成單級電路,若是能夠在加強安定器的功能讓它可以 隨插即用各種瓦特數的複金屬燈,也是一個未來極待努力的方向。
