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。
With the rapid development of electronic technology, the function of various devices such as mobile phones, laptops, PDA is more and more abundant, and the supply voltage varies. Existing integrated power chips have been unable to meet the power needs and performance requirements of these devices. So adjustable high power DC-DC Converter research has an important practical significance. This design puts forward a DC-DC method based on DSP. Experiments show that this DC-DC Converter can transform DC 12 V to ad- justable DC 24 V - 32 V. The maximum power supply of the Converter is 30 W. Voltage fluctuation is small and DC-DC conversion ef- ficiency reaches higher. So it has a certain practical application to high voltage stability requirements equipment.
