宽范围TA取能电源

摘要
在线监测设备的可靠工作对电源性能有较高的要求,为提升取能电源的供电性能,基于无源元件设计了1套TA取能电源。为了解决TA取能电源难以兼顾高取能效率和避免饱和的难题,选取高磁导率的纳米晶合金作为铁芯材料,通过理论分析和仿真研究,分析匝数、负载阻抗对取能效率的影响;同时采用肖特基二极管组成稳压泄流通路抑制铁芯饱和。利用整流桥和直流–直流变换器(DC-DC)模块实现稳定直流电压的输出,通过有限元电磁–热耦合仿真并结合试验设计合理的电源装置。该电源装置可在导线电流在17～1 100 A范围内为摄像头负载提供1.5 W以上的电能。
The reliability of online monitoring equipment has a high demand on the performance of power supply. To improve the power supply performance of the drawout power, we designed a set of TA power supply based on the passive components. In order to solve the problem that the TA power supply is difficult to consider high efficiency and saturation simultaneously, nanocrystal line alloys with high permeability were selected as core materials. Based on theoretical analysis and simulation study, the influences of turns number and load impedance on power acquisition efficiency were studied.Meanwhile, current discharge circuit made of Schottky diodes were applied in the power supply to suppress core saturation. The rectifier bridge and DC-DC module were used to stabilize and smooth the DC output voltage. The reasonable power source device was designed through electromagnetic-thermal coupling calculation and test. The proposed power supply can offer more than 1.5 W power while the current value of line is within range of 17 A to 1 100 A.
