摘要
针对常规DC-DC变换器输出电压调整困难、反馈实现复杂、智能化程度低的问题,提出了一种新型的能够根据用户要求快速改变输出电压的DC-DC变换器,并且能够根据电源输入的电压变化情况实时调整控制参数,实现稳定的电压输出,且输出电压不受输入电压变化的影响。通过对不同负载和电源输入变化的实验验证,该DC-DC变换器具有输出电压稳定精确、纹波率小、反馈快速准确的特点,对于某些对输入电压稳定性要求高的场合有实际应用意义。
Against the fact that the voltage values of DC-DC converter is difficult to adjust due to complex feedback and low degree of in-telligence,this paper proposes a new type of DC-DC converter that can be adjusted easily.This converter can adjust the control parame-ters along with the input voltage,keeping the output voltage stable.Experiments of different loads and input voltage show that this DC-DC converter has the advantage of stable output voltage,low voltage fluctuation,quick and accurate feedback.It has practical meaning in terms of requiring stable output voltage.
