基于DSP56F8323的移相全橋軟開關DC-DC變換器

摘要：隨著技術的發展，模擬控制的固有缺點限制了它的應用場合，數字控制已成為新的趨勢。本文介紹了Motorola一種新的DSP―DSP56F8323，并將其用于移相全橋軟開關DC-DC變換器。取得了較好的控制效果，并實現了較好的動態特性。 敘詞：DSP、移相全橋 Abstract：With the development of technology, the inherent disadvantage of analog control confines it’s application field, digital control has been a new tendency . A new kind DSP is introduced in the paper－DSP56F8323,which comes from Motorola. The DSP is applied in the Phase－Shifted Full—Bridge topology which achieves the aim of soft switch. The good performance is gained and also the dynamic characteristic. Keyword：DSP、Phase—Shifted Full Bridge
