【摘要】：隨著電子技術的高速發(fā)展,各式設備如手機、筆記本電腦、PDA等的功能日趨復雜,性能不斷提高,需求的供電電壓也不盡相同�，F(xiàn)有的集成電源芯片已無法滿足這些設備的功率需求和性能要求,因此對可調高功率DC-DC變換器的深入研究有很重要的實際意義。提出一種基于DSP芯片的DC-DC變換器設計方案。通過實驗驗證,該變換器實現(xiàn)了直流電壓12 V-24 V的轉化,且輸出電壓可以在24 V-32 V之間調節(jié),用戶可以根據(jù)實際的需求進行調整。與此同時,該變換器的輸出功率可達到近30 W,且輸出紋波電壓小,DC-DC變換效率較高,對輸入電壓穩(wěn)定性要求高的設備有一定的實際應用意義。
[Abstract]:With the rapid development of electronic technology, the functions of all kinds of devices, such as mobile phone, notebook computer, PDA, etc., are becoming more and more complex, the performance is improving, and the power supply voltage is not the same. The existing integrated power chips can not meet the power requirements and performance requirements of these devices, so it is of great practical significance to study the adjustable high power DC-DC converters. A design scheme of DC-DC converter based on DSP chip is proposed. The experimental results show that the converter realizes the conversion of DC voltage 12 V 鈮，
