設計數位控制器 操作於不連續導通模式之降壓型轉換器

Design of a Digital Controller for a Buck Converter Operating in Discontinuous Conduction Mode

指導教授 : 陳德玉

摘要


使用數位控制器的直流電源轉換器,提供了電源設計者更好的設計空間與更靈活的設計彈性,且數位控制器又具有線上調整之功能。 本論文,探討降壓型轉換器操作在連續導通模式與不連續導通模式下之數位控制設計與分析,並且強調轉換器於不連續導通模式之控制器設計方式。並使用德州儀器公司所生產DSP,TMS320LF2812,實現不連續導通模式、與導通模式之數位式降壓型轉換器。 本論文依降壓型轉換器的規格,輸入電壓3V,輸出電壓1.5V,且在負載變動條件下,觀察輸出電壓之穩定性,並且推導出不連續導通模式轉換器之小訊號數位等效模型。

DC Power Converter with a digital compensator provides design flexibility and the possibilities of on-line adjustment of compensation. In this thesis , digital compensation designs for the converter working in both the continuous conduction mode (CCM) and the discontinuous conduction mode (DCM) are described with emphasis on DCM operation. Experiments were also conducted using a DSP ,TMS320LF2812,to implement the compensator.
