摘要
随着电力电子技术的发展,开关电源也朝着小型化、高效、高精度的方向发展。设计一种采用Buck型降压电路进行降压,以DSP芯片TMS320F28027为主控制器,通过模糊控制方法控制电压和电流稳定输出,同时具有可靠闭环控制的直流稳压电源。该直流稳压电源能够提高开关电源的精度和效率,也使设计成本大大降低。实验结果表明,相比于传统设计方法,采用该设计后整机效率最高可达92.01%。
With the development of power electronic technology,switching power supply technology is improved continually toward miniaturization,high efficiency and high precision.Based on the development trend of switch power supply,the paper designs a DCvoltage-stabilized source that adopts a type of buck step-down circuit to improve the step-down,regards DSP chip TMS320 F28027 as the main controller to realize stable output of voltage and current through fuzzy control and also possesses reliable closed-loop control.The designed DC voltage-stabilized source can realize high precision and high efficiency of switching power better,and also save the design-cost greatly.The result of experiment shows that the maximum overall efficiency can reach 92.01% by this design when compared with traditional design.
