【摘要】：随着电子技术的高速发展,各式设备如手机、笔记本电脑、PDA等的功能日趋复杂,性能不断提高,需求的供电电压也不尽相同。现有的集成电源芯片已无法满足这些设备的功率需求和性能要求,因此对可调高功率DC-DC变换器的深入研究有很重要的实际意义。提出一种基于DSP芯片的DC-DC变换器设计方案。通过实验验证,该变换器实现了直流电压12 V-24 V的转化,且输出电压可以在24 V-32 V之间调节,用户可以根据实际的需求进行调整。与此同时,该变换器的输出功率可达到近30 W,且输出纹波电压小,DC-DC变换效率较高,对输入电压稳定性要求高的设备有一定的实际应用意义。
[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，
