【摘要】：针对现有电流互感器取能电源存在供电死区的现象,提出了一种可适应较小电流电力母线的电流互感器取能电源供电方案。在分析电源取能原理的基础上,建立了电流互感器取能电源的电路模型,并推导了电源取得最大功率的条件。选择高饱和磁感应强度的硅钢材料作为铁芯,设计了五级电荷泵电路、能量收集电路以及电源管理电路。基于所提出的方案研制了样机,以无线测温模块作为负载,对样机整体进行了测试。实验结果表明,当电流在1~1 000A范围内时,电源工作于非饱和低热耗状态。
[Abstract]:In view of the phenomenon that the existing current transformer energy-taking power supply has a dead zone, this paper presents a power supply scheme of the current transformer energy-taking power supply which can adapt to the lower current power bus. Based on the analysis of the principle of the power supply, the circuit model of the current transformer energy-collecting power supply is established, and the condition of obtaining the maximum power of the power supply is deduced. Five-stage charge pump circuit, energy collection circuit and power management circuit are designed by selecting silicon steel material with high saturation magnetic induction strength as iron core. The prototype is developed based on the proposed scheme, and the whole prototype is tested with the wireless temperature measurement module as the load. The experimental results show that when the current is in the range of 1 000 A, the power supply works in the state of unsaturated low heat consumption.
