一种直流侧带电感的稳压滤波电路
摘要：
本发明公开了一种直流侧带电感的稳压滤波电路，包括与直流源输入相连的直流侧稳压支路，直流侧稳压支路并联纹波吸收支路，且在并联支路上连接有用于增大直流侧稳压支路阻抗的电感组件，使得直流侧稳压支路的电流减小，纹波吸收支路的电流增大。所述的电感组件采用空心电感、带磁芯电感以及能够达到要求电感量的导线中的任意一种。本发明在相同的直流源工况下，使得直流侧稳压支路的电流减小，纹波吸收支路的电流增大，这样就能够使得直流侧稳压支路的电容热损减小，而纹波吸收支路的电容热损增大，增大直流侧稳压支路电容工作的稳定性，提高电容的使用寿命。
摘要（英）：

The invention discloses a DC side voltage stabilization filter circuit equipped with an inductor. The DC side voltage stabilization filter circuit comprises a DC side voltage stabilization branch which is connected with DC source input. The DC side voltage stabilization branch is connected in parallel with a ripple absorption branch, and an inductor component used for increasing the impedance of the DC side voltage stabilization branch is connected on the parallel branch so that the current of the DC side voltage stabilization branch is enabled to be reduced and the current of the ripple absorption branch is enabled to be increased. Any one of a hollow inductor, an inductor with a magnetic core and a lead capable of realizing the required induction is used as the inductor component. The current of the DC side voltage stabilization branch is enabled to be reduced and the current of the ripple absorption branch is enabled to be increased under the same DC source condition so that the capacitance heat loss of the DC side voltage stabilization branch is enabled to be reduced and the capacitance heat loss of the ripple absorption branch is enabled to be increased, the working stabilityof the DC side voltage stabilization branch capacitor can be increased and the service life of the capacitor can be enhanced.
