小体积低纹波DC/DC变换器设计

Small Low Ripple DC/DC Converter Design

介绍了一种小体积低纹波DC/DC变换器的设计过程。依据设计目标参数,对设计方案进行选择,介绍了正激式拓扑结合反相器方案中主要器件选型和设计以及调试遇到的问题。改进设计方案,通过反激式拓扑和低压差稳压器相结合实现了小体积低纹波的DC/DC变换器设计。

This paper introduces a kind of small volume,low ripple of DC/DC converter design process.According to the design target parameters,the design scheme selection,this paper introduces the scheme of forward type topology in combination with the inverter in main device selection and design,and debugging problems.Then improved design scheme,through the combination of the flyback topology and Low-Dropout Regulator(LDO)to implement small volume,low ripple of DC/DC converter design.
