數字技術在開關電源控制中的應用和發展

摘要：本文首先介紹了用于電源控制的數字芯片的發展現狀，介紹目前用數字芯片實現電源控制的兩種方法，并指出這兩種方法存在的問題。然后介紹一種用于開關電源的新型控制技術，該技術現在已經開始在一些數字芯片上得到應用，相信將會是未來電源控制技術的發展趨勢。 敘詞：開關電源 數字控制 控制處理器 Abstract：Digital control technique haven’t been widely used in power supply now. Because two digital control methods which have been used in power supply have their drawbacks. We introduce a new control technique that mainly used in power supply, and it has been used in some digital ICs. I think it will be the trend of the digital control technique of power supply.
