【摘要】：隨著電子技術(shù)的高速發(fā)展,各式設(shè)備如手機(jī)、筆記本電腦、PDA等的功能日趨復(fù)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(shè)備的功率需求和性能要求,因此對可調(diào)高功率DC-DC變換器的深入研究有很重要的實(shí)際意義。提出一種基于DSP芯片的DC-DC變換器設(shè)計(jì)方案。通過實(shí)驗(yàn)驗(yàn)證,該變換器實(shí)現(xiàn)了直流電壓12 V-24 V的轉(zhuǎn)化,且輸出電壓可以在24 V-32 V之間調(diào)節(jié),用戶可以根據(jù)實(shí)際的需求進(jìn)行調(diào)整。與此同時(shí),該變換器的輸出功率可達(dá)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(shè)備有一定的實(shí)際應(yīng)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，
